MATTER, Definition, States, and Change of State
At the conclusion of our time together, you should be able to:
1. Define matter2. Define the various states of matter and
draw an example of each state3. Recognize that particle motion
determines the state of matter

Matter:
Anything that has mass and takes up space
Matter is made up of building blocks:atom – smallest unit of an element.element – a pure substance made of only one kind of atom.compound – made of two or more atoms that are chemically combined.

FYI
90% of the Earth’s crust is made up of only 5 elements:
Oxygen 49.2%Silicon 25.7 %Aluminum 7.5%Iron 4.7%Calcium 3.4%

States of Matter
Solid- Definite volume and shape Particles are tightly packed Slight expansion when heated Incompressible

Liquid- Has definite volume, but no definite
shape (assumes the shape of the container)
Particles are loosely packed (can flow by sliding over each other)
Easily expand when heated Considered incompressible

Plasma- Consists of electrically charged
particles It’s an ionized gas Common in space, but very rare on
Earth Found in lightning, fluorescent lights
and neon signs

Energy Amounts in States of Matter
Solid- little energy, particles vibrate and rotate
Liquid- more energy, they move freely by sliding over each other
Gas- even more energy, move quickly Plasma- most energy, move extremely
fast
