Molar Heat Capacity at Cp s. Cv

[Angela Prince 1J]

I am kinda confused on the differences between the molar heat capacity of a gas at constant volume versus constant pressure. Why does it matter in terms of molar heat (is it applicable for specific heat as well)? Can you use the q=nCdeltaT equation for either situation?

[Kate Osborne 1H]

molar heat capacity of the same gas is different at a constant pressure vs a constant volume, you can use that equation with both Cp and Cv it would just result in a different answer for Cp vs Cv

Subscript p refers to constant pressure and subscript v refers to constant volume.

[Ayushi2011]

P is the constant pressure and V indicates temperature.

Both can be used for a gas, however they do not yield the same answer. The p subscript indicates constant pressure while the v is for volume.
