Part 1: The Kinetic Molecular Theory and Phase Changes
1. Label the phase diagram with the following:
Solid, liquid, gas phase, freezing point, boiling point, melting point, condensation,
evaporation, melting
2. What type of energy is involved in heating a substance that is in one state
of matter?
3. What type of energy is involved in changing the phase of matter?
4. Why is it possible for the melting point and freezing point to happen at the
same temperature as well as the boiling point and point of condensation to
be at the same temperature?
5. If a solid is changing to a liquid it is because heat is being
6. If a gas is changing to a liquid it is because heat is being (added/removed)
from the system.
