Heat capacity

Postby Michael Lee 2I » Fri Jan 12, 2018 5:53 pm

How is heat capacity a state function if it is an intensive property?

I thought heat capacity was an extensive property?

I believe heat capacity is an extensive property where as specific heat capacity and molar heat capacity are intensive properties. And to elaborate, I think molar heat capacity at a constant pressure is considered a state function.

Yes heat capacity is an extensive property and not an intensive property

Heat capacity is an extensive property because it does depend on the amount of substance. However, specific heat capacity is per gram of substance and molar heat capacity is per mole of substance, so they are intensive properties.
