Cv and Cp
Why is the heat capacity for constant pressure greater than the heat capacity at constant volume?

Re: Cv and Cp
At constant volume, the heat goes towards raising temperature but at constant pressure, some go towards work.

Re: Cv and Cp
Under constant pressure, some of the heat can go into doing work in order to expand or compress against the surroundings. Under constant volume, no work can be done.

Re: Cv and Cp
When heat is added under constant pressure, the substance expands and does work, whereas when heat is added under a constant volume, no work is done.
