1. Matter - anything that has mass and takes up space

Four states of matter:

Solid
Liquid
Gas
Plasma

Viscosity - a fluid's resistance to flow

Vapor - a substance that exists as a gas (when it should normally be a liquid or solid)

2. Changes of State

Energy

- Kinetic - energy an object has due to motion

- Thermal - total kinetic energy of all particles in a substance

Difference between temperature, thermal energy and heat

- temperature - average kinetic energy of particles in a substance

- thermal energy - total kinetic energy of all the particles in a substance

- heat - movement of thermal energy

What causes changes?

- dding or taking away thermal energy

Types of changes

- vaporization - change from liquid to gas, boiling point

- solid - change from liquid to solid

- condensation - change from liquid to solid

- melting - change from solid to liquid

- sublimation - liquid to gas

3. Behavior of Fluids

Fluids

- be able to flow

- no definite shape

Laws of Gasses

- Boyle's Law: increased pressure, decreased volume; decreased pressure, increased volume. Changing one variable causes the other to change in the other direction. (Inverse relationship)

- Charles' Law: temperature decreases, volume decreases; temperature increases, volume increases. Both variables change in the same direction. (direct relationship)
