Chem- Quiz 3

Chemistry States of Matter and Gas Laws

Heat Thermal energy. This is actually the kinetic motion of the particles within a substance.
Temperature The measure of how much heat is in a substance.
Kelvin Scale Temperature scale that measures the absolute temperature of a substance.
Sublimation The change of state from a solid directly to a gas (like dry ice).
Deposition The change of state from a gas directly to a solid (like frost on a cold morning).
Condensation The change of state from a gas to a liquid.
Vaporization The change of state from a liquid to a gas.
Melting The change of state from a solid to a liquid
Freezing The change of state from a liquid to a solid.
Plasma The state of matter where molecules have the most kinetic energy. Most matter in the universe is in this state.
Solid The state of matter where molecules have the least amount of kinetic energy. Molecules are packed closely together. The substance has definite shape and volume.
Gas The state of matter that does not have definite shape or volume. Molecules need more space and bounce off of each other.
Liquid The state of matter that has definite volume, but not definite shape. Molecules slide past each other.
Phase Change A physical change from one state of matter to another.
Absolute Zero The coldest possible temperature (-273C). Particles have no kinetic energy at this temperature.
