Question | Answer |
---|---|
What is the freezing point of water? | 32*F = 0*C |
What is the boiling point of water? | 212*F = 100*C |
What is the temperature of a substance as the amount of heat increases during a temperatures phase changes? | The temperature stays the same |
What are the three states of matter? | Solid, Liquid, Gas, and Plasma |
SOLID | - Particles of solids are tightly packed, vibrating about in a fixed position - Have a definite shape and volume |
LIQUID | -Particles of liquid are tightly packed, but are far enough apart to slide over one another - Have an indefinite shape and volume |
GAS | - Particles of gases are very far apart and move freely/rapidly - Gases have an indefinite shape and volume |
STATES OF MATTER | - Based on particle arrangement - Based upon energy of particles - Based upon distance between particles |
Kinetic Theory Of Matter - | Matter is made up of particles which are in a continual random motion |
