Re: Specific Heat Capacity vs. deltaHfus and deltaHvap
The specific heat capacity is the amount of energy it takes to raise a certain unit of mass a certain unit of temperature. Usually this unit of mass is grams and the unit of temperature is Celsius or Kelvin. For example 1 calorie is the amount of energy it takes to raise the temperature by one degree Kelvin/Celsius of one gram of water. Delta H fusion is the amount of energy it takes for a substance to change from solid to liquid. Delta H vaporization is the amount of energy it takes for a substance to change from liquid to gaseous. Delta H sublimation is the amount of energy it takes for a substance to change from its solid phase to its gaseous phases. These last three values do not take amount into account, so in their units they have energy/moles: multiplying by the moles gives the value for a certain quantity of that substance.

Adding onto the previous post, since those three terms don't depend on the amount of substance into account, they can be described as intensive properties.
