Molar heat capacity at constant volume is …………….

1.	Molar heat capacity at constant volume is …………….
Answer» Solution :According to the FIRST law of thermodynamics, dy = dU + PdV Dividing both sides by dT , we have `(dq)/(dT)="(dU+PdV)"/(dT)` At constant VOLUME dV=0 , then `(dq)/(dT)=((dU)/(dT))_(v)` `C_V=((dU)/(dT))_V` THUS the heat capacity at constant volume `(C_V)` is DEFINED as the rate of CHANGE of inter energy with respect to temperature at constant volume.
