| A | B |
|---|
| kinetic energy | energy of motion |
| kinetic theory | how particles in gases behave |
| melting point | temperature at which solid becomes a liquid |
| heat of fusion | energy required to change solid to liquid at melting point |
| boiling point | temperature at which pressure of vapor in liquid is equal to external pressure acting on surface of liquid |
| heat of vaporation | amount of energy required for liquid at boiling point to become gas |
| sublimation | process - solid changing directly to gas (no liquid) |
| plasma | matter that has enough energy to overcome atractive energy between particles and in atoms |
| thermal expansion | increase in size when temperature increases |
