Physical and Chemical Properties

A property is a characteristic or a description of something

(Write down things in purple)

Our properties make us what we are

Some of Malfoy’s properties include

Ice Blue EyesShort, White-Blonde HairSneering SmileDesire for powerFamiy richesDislike of Muggles

Physical Properties of Matter

A. Things that can be measured with the

metric system

length weight or mass density boiling point freezing point

Mercury (a liquid) is more dense than lead. May be we should say “Get the MERCURY out”, not “Get the lead out.”

Solid water is less dense than liquid water. That’s why ice cubes float in water.

Weight is actually measured in Newtons, not grams.

Physical Properties Trivia

B. Inertia – matter at rest will stay at rest matter in motion will stay in motion

Physical Properties of Matter

Physical Properties of Matter

C. Things that can be determined with the

senses

Color Texture Hardness Luster (shiny-ness) Taste Shape Odor

Sulfur can be identified by its “rotten egg” smell.

Diamond is the hardest mineral we know of.

Halite tastes like salt.

Physical Properties Trivia

Physical Properties of Matter

D. Describe the phase of matter of the

substance

solid semi-solid (amorphous) liquid gas plasma

Chemical Properties of Matter

A. Describe the way matter interacts

These interactions are sometimes called chemical reactions

Chemical Properties of Matter

In actual chemistry classes, you’ll learn how the electrons of individual atoms of matter combine or transfer to make new compounds.

(aren’t you glad we don’t have to learn that yet?)

Some common chemical properties involving oxygen

B. Oxidation Reactions Oxygen and iron react to

form iron oxide (rust)

Oxygen and hydrogen react to form water

Oxygen and copper react to form copper oxide

Some common examples of chemical properties of acids and bases

C. Acid-Base Reactions

Zinc fizzes in hydrochloric acid

Hydrochloric acid bubbles and fumes on limestone

Vinegar bubbles and foams when in contact with baking soda

Some common examples of chemical properties of electrical reactions

D. Electrical Reactions When electricity is passed

through water and acid, hydrogen and oxygen gasses are released

When electricity is passed though an acid solution with a metal object inside, and a copper diode, the metal becomes “plated” with copper

Some common examples of chemical properties of reactions between

substances

Sodium + chlorine = salt

Silver + sulfur = silver sulfide

(tarnish)

candle burns?
