I've read that:
specific heat capacity at constant pressure = dU-W / m. dT
dU = change in internal energy
W = work done
m = mass of gas
dT = change in temperature
-----------------------------------
However, shouldn't the right hand side equate to specific heat capacity at constant VOLUME?
By saying that it is specific heat capacity at constant pressure, I thought we have already taken into account the energy used to expand the gas.
