Heating Curves

Heating and Cooling curves are used to describe the phase changes as a solid is heated or a gas is cooled. You must be able to label all phase changes and draw these graphs when given appropriate data.

1 - 2: Heating of a Solid

2 - 5: Melting of a Solid (Fusion)

5 - 10: Heating of a Liquid

10 - 14: Boiling of a Liquid (Vaporization)

14 - 16: Heating of a Gas

1 - 3: Cooling of a Gas

3 - 7: Condensation of a Gas

7 - 12: Cooling of a Liquid

12 - 15: Freezing of a Liquid

15 - 16: Cooling of a Solid

Sublimation - Occurs when a solid changes directly into a gas

Deposition - Occurs when a gas changes directly into a solid
