Solid -> Liquid
Particles in a solid:
- Packed
- Vibrating in fixed positions
- Forces of attraction is very strong
Gaining heat:
- Kinetic energy increases
- Forces of attraction weakens
- Vibrating more vigorously
 |
At 2, Heat energy that is converted to Kinetic Energy is used to overcome the force of attraction, and thus no heat is gained.

Particles of the liquid (after heat gain)
