1. Indefinite articles: the articles a and an are called indefinite articles because they do not point to a particular person or thing.

Exercise B.One day, my parents had an idea. They said that they would like to buy a house. We were thrilled: A house of our own! Then our parents became quite obsessed with the idea till they bought the house last month. The house has four bedrooms, a huge garden in front and a kitchen garden at the back.’ This is the house I used to dream of', my father said. The only person who is not entirely thrilled is my sister. She doesn't quite like the living room because of insufficient natural light. That’s an important point, she said. We agreed with her and decided to get some renovation

Uses of Indefinite articles :1) We use a and an before countable nouns in the singular number. For example, a desk , an orange.2) We use a before words that begin with a consonant sound. We use an before words that begin with the vowel sound. For example, thirsty crow, a good friend an empty bottle and independence state. 3)We use a before words that begin with t and u because they have an initial why sound. for example, a university, a European.4) We use a before words that begin with o but sound like' w'. Example a one-story building.5) We use an before words that begin with a silent 'h' for example and hier an honest politician.6)We use and before abbreviations, if counselling begins with the vowel sound. For example and MLA and MP.2. Definite articles: The is called The definite article because it points to a particular person or a specific thing. Uses of definite Articles : a)We use the winner singular common noun is used to indicate a whole class.b)We use the with objects that are unique.c)we use the before names of trains planes ships of well known buildings and institutions coma names

CHAPTER- Medieval Europe-Rise and Spread of Christianity

History is divided into three periods—early middle or medieval and modern periods.Word ‘medieval’ is derived from latin word mean time in the middle. It is further subdivided: Early medieval period ( 9th and 12th century) and later medieval period (13th and 18th century).Meaning of Christianity;Word ‘Christian’ refers to the followers of Jesus Christ. Christianity is a religion that is based on the teachings of Jesus Christ. The Christian calendar marks the birth of Jesus at 4 BC. BC stands for Before Christ and AD stands for Anno Domini which in Latin means in the year of our Lord. Jesus was born in Bethlehem near Jerusalem. His entire thinking was based on the central idea that God is the loving father of all. His teachings were very simple.

1) What is the word medieval mean?Ans: The word 'medieval' is derived from the Latin word mean time in the middle.2) What is the word Christianity mean?Ans: The word Christian refers to the followers of Jesus Christ. Christianity is a religion that is based on the teachings of Jesus Christ.3) When was Jesus Christ born?Ans: Jesus Christ was born at 4 BC.4) What does BC and AD stands for?Ans: BC stands for Before Christ and AD stands for Anno Domini which in Latin means in the year of a Lord.5) Give any two main teachings of Jesus Christ.Ans: God is our Father. We should love Him.God is ever-forgiving , ever- loving and kind.

Mathematics Topic-Number System.Chapter-Integers

Study item: Division of integersDivision is a inverse process of multiplication.Example: 30÷5=6Again, 6×5=30Important notes:(i) when two integers with same sign divides we get positive integer.Example: 45÷9=5 where 45 and 9 are positive integers.-33÷(-11)=3 where -33 and -11 are negative integers.(ii) When two integers with different sign divide we get negative integer.Example: -50÷5=-10 where -50 and 5 are integers with different sign.Study Item: properties of division of integers.

(i) When two integers divide we cannot get integer as a result in all the case.

Example: 23/5 which is not an integer.(ii) When a non- zero integer divide by itself we get result 1.

Example: -7÷(-7)=1 and 27/27=1(iii) When an integer which is non-zero divide by 1, and we get the

same non-zero integer. Example:35÷1=35

(iv) When 0is divided by a non-zero integer we get 0 as a result. Example: 0÷4=0 But its reciprocal is not true. Example: 4÷0= not any result, because it is meaningless. Study item: Using DMAS rule When there is more than one operation in a sum at that moment, we use DMAS rule. That mean first we perform division, then multiplication, then Addition and finally subtraction.Example: 5+(-48)÷(-16)+(-2)×6=5+3+(-2)×6 perform division=5+3+(-12) perform multiplication=8-12 perform addition=-4 perform subtraction.

Physics Kinetic Theory of Matter.

Three states of matter in terms of movement of particles.

Energy content in the three states of matter.

Kinetic theory of matterMolecules of matter are in a continuous state of motion. Hence, they possess kinetic energy. The kinetic energy of molecules increases with an increase in temperature and decreases with a decrease in temperature. The molecules of matter always attract each other and the force of attraction between them is known as force of cohesion which binds the molecules of a substance together. This force is maximum between the molecules of solids, lesser between the molecules of liquids and least between the molecules of gases. The force of attraction between the different types of molecules is called the force of adhesion.The force of attraction between the molecules (either cohesive or adhesive) is called the intermolecular force of attraction. The space between any two consecutive molecules is called the intermolecular space. If the intermolecular force of attraction increases, the intermolecular space decreases, and vice versa.Arrangement of MoleculesSolidsMolecules are very tightly packed and have least intermolecular space between them. The intermolecular force of attraction holds the molecules at one place with very small vibrations. Molecules cannot move easily from

their positions because their kinetic energy is low and are not enough to let them break away from their mutual force of attraction. Therefore, solids have a definite shape and volume and are not compressible. For the same reason, they do not flow or diffuse. Also, solids are rigid and hard and are difficult to break because of the strong force of attraction between the molecules.LiquidsMolecules are less tightly packed in liquids and attract each other with a lesser force as compared to solids but not enough to make liquids compressible.They do not stay at the same position as the intermolecular

force of attraction between them is less.The kinetic energy of the particles is more in liquids as compared to solids and the particles are not bound to any fixed positions. They move around freely, at random, throughout the liquid. However, they do not have enough kinetic energy to break out of the boundary of the liquid mass. This is the reason that liquids do not have definite shapes and flow or diffuse freely, but they have definite volumes.GasesIn gases, the molecules are very loosely packed and the force of attraction is the least as compared to solids and liquids.

The kinetic energies between the molecules are high enough to let them break away from any boundaries. They are free to move around in random motion. Thus, gases can change their shape and volume easily and can be compressed to fill any container.Example: Petroleum gas is compressed and filled in the cooking gas cylinders which we use in our kitchen to cook food.

VERB AGREEME

In ‘subject-Verb-Agreement’ a singular verb takes a Singular verb and a plural verb takes a plural verb.

NT (CHAPTER-5)

In a sentence where a pronoun is the subject, the verb must agree with the number and the person of the pronoun.The verb forms with I, we, you, and they is same.eg- I/ we/ you/ They have little money left.For ‘be’ verbs, the form remains the same with the pronouns we, you, and they, but it is different for ‘I”.eg- I am skilled at sports.The concord for all verbs remain the same with the pronouns he, she and it.eg- My dog is very well behaved, it does not bark at my acquaintances.

Now we know about cell theory.

There is some classification of organisms according to number.

Q1. What is microscope? Classify it.A piece of equipment that makes very small objectsLook big enough for you to be able to see them.• Antony van Leeuwenhoek made simple microscope with one lens and one adjustment screw. It had a magnifying powercope up to 200 times.• Robert Hooke made compound microscope with two lenses and two adjustment screws. It magnifies up to 2000 times. He examined a thin slice of cork and observed "box like" compartment. He said these are all “cells”• Electron microscope : which gives us a magnification over 200,000 times by using beams of electrons which are bent by magnets.Q2. State cell theory.• The cell is the smallest unit of structure of allliving things.• The cell is the unit of function of all living things.• All cells arise from pre-existing cells.Q3. Classify organism according to number of cells.• Single-celled : made up of one cell. ex: yeast, bacteria, amoeba.• Few-celled: made up of a few hundred to few thousand cells. ex: volvox, Spirogyra• Multi-celled: made up of millions and billions of cells. 'ex: Human, Mango• Smallest cell - Bacteria 0.3- 5.0 micrometer.• Longest cell - Nerve cell - 135 micrometer.• Largest cell – Ostrich egg - 20 cm in diameter.

ENGLISH LITERATURE

THE HEART OF A TREE

The heart of a tree by Henry Cuyler Bunner.The main theme of this poem is “what does he plant who plants a tree?” The poet says that it’s not just a tree we plant but a friend of sun and sky. And he describes the tree to be the flag of breezes free. And that it as the shaft of beauty that towering high. He says that we plant a home to heaven and for song and mother-croon of bird. This brings cool shade and tender rain and the seeds and buds of tomorrow. He says that tree is the glory of the plain and forest’s heritage. And the harvest of a coming age is the joy that unborn eyes shall see. One plant a tree in love of home and loyalty. And the poem has a very beautiful ending which says that, “A nation’s growth from sea to sea. Stirs in his heart who plants a tree.” This means that one who plants a tree would bring blessings and that helps in the nation’s growth.

Questions1.“The same activity may be commercial as well as Non

Commercial at different times”.Comment. Answer: An activity weather considered as commercial and Non Commercial depends on the motive behind performing such activities. For instance, a teacher teaching roadside children’s spontaneously is Non Commercial activities since it does not involve money earning motive, but if that same person is teaching in school is a commercial activities since the motive is to earn money.

2. Give two examples of direct serviceAnswer:-Direct service means providing services through person to person contact. Such services provided by qualified person. Example :i) Doctor treating a patient at his own chamber .ii) House maid providing service at home.

3. Classify the following into commercial and noncommercial activities:i. A tea stall on New Delhi railway station.

ii. Sarita preparing tea for her husband.iii. Hasina nursing her mother in law.iv. A yoga teacher teaching yoga to clients.

Mathematics

Topic-Pure ArithmeticChapter-Rational and Irrational numbers.

A number which cannot be expressed as p/q form where p and q are integers and q not equal to is called Irrational number.Example:√2,√3,√5,2+√3 etc. To prove a number Irrational number, we have to learn The two theorems.Theorem 1: If a,n are any natural numbers and p is a prime number such that p divides an, then p divides a.Theorem 2: If a and b are any natural numbers and p is a prime number such that p divides an then p divides a or p divides b or provides both.

Prove that √5 is an irrational number.Solution: Let √5 be a rational number, then√5=p/q where p and q are integers and q not equal to zero and p,q have no common factors except1.Or,(√5)2=(p/q)2Or, 5 =p2/q2Or, p2=5q25 divide 5q2, so, 5 divides p2 where 5 is prime number.5 divide p.Again let, p=5m where m is an integer.then(5m)2=5q2Or, 25m2 =5q2Or, 5m2=q25 divide 5m2, so, 5divides q2 where 5 is prime number.5 divides qFrom the above result we see p and q have common factor 5.Which contradicts our assumption.Therefore, √5 is an irrational number.

1.Symbols based on latin names2.Chemical symbols3.Valency4.Radical5.Writing chemical

formulae.

1. What is a symbol? What information does it convey?Solution:Short form of atom of specific element or the abbreviations used to refer names of the element is known as symbol.1. It represents a specific element.2. It represents one atom of an element.3. A symbol represents how many atoms are present in its one gram (gm) atom.4. It represents the number of times an atom is heavier than one atomic mass unit (amu) taken as a standard.2. Why is the symbol S for Sulphur, but Na for Sodium and Si for Silicon.Solution:While naming an element first letter of the elemnt is taen and written in capitals(e.g. for sulphur, we use the symbol S). In case if the letter is already adopted. We use a symbol derived from latin word of the element name (e.g. for sodium/Natrium, we use the symbol Na). In some cases, we use the initial letter in capital together with a small letter from its name (e.g. for silicon, we use the symbol Si).3. Write the full form of IUPAC. Name the elements represented by the following Symbols: Au, Pb,Sn,HgSolution:IUPAC stands for The International Union of Pure and Applied Chemistry (IUPAC).Au- GoldPb- LeadSn- TinHg- Mercury4. If the symbol for cobalt, Co were written as CO, What would be wrong with it.Solution:If we write CO it means it consist of two non-metals namely Carbon and Oxygen and it would represent Carbon-monoxide but not Cobalt.5. What do the following symbols stand for?a) H b) H2 c) 2H d) 2H2

Solution:a) H stands for one atom of Hydrogenb) H2 stands for one molecule of Hydrogenc) 2H stands for 2 atoms of Hydrogend) 2H2 stands for 2 molecules of Hydrogen.6. What is meant by atomicity? Name a diatomic element.Solution:A set of atoms of the same type together forms a molecule of the element. The number of atoms in a molecule of an element is called its atomicity.Examples of diatomic elements are H2- Hydrogen, O2- Oxygen, N2-Nitrogen7. a) Explain the terms valency and variable valency?b) How are the elements with variable valency named? Explain with an example.Solution:Valency is the capacity of an atom to lose, gain or share atoms during a chemical reaction is called its valency.Sometimes atom of an element can lose more electron than they are present which means they lose electron from its penultimate shell. Such an element is said to exhibit variable valency.b) If an element exhibits two different positive valencies, then1. For the lower valency, use the suffix -OUS at the end of the name of the metal

2. For the higher valency, use the suffix -IC at the end of the name of the metal.8. Give the formula and valency ofa) aluminateb) chromatec) aluminiumd) cupric
