  14. Heat Capacity
    Is the proportionality constant between the heat that the object absorbs or loses and the resulting temperature change of the object,

    Q=CΔT
  15. Specific Heat

  17. Molar Specific Heat
    When quantities are expressed in moles, specific heat must also involve moles (rather then a mass unit).
  18. Heat of Transformation
    The amount of energy per unit mass that must be transferred as heat when a sample completely undergoes a phase change.

    Q=Lm
  19. Heat of Vaporization
    When the phase changes is from liquid to gas or from gas to liquid.
