Why is heat capacity a state function?

Postby Skyllar Kuppinger 1F » Tue Feb 11, 2020 7:29 pm

There was a problem from the review session that asked which things are state functions, and it said that heat capacity was a state function. Why is this the case? Isn't heat capacity an inherent property of a substance? I understand that entropy , for example , is a state function because change in entropy is just based on final minus initial and isn't dependent on the pathway you took to get to that final state. How does this principle apply to heat capacity?

Because it does not matter HOW the heat was added or HOW much the temperature changes.
