Answer» Solution :We know, H=U+PV Differentiating the above equation with respect to temperature at CONSTANTPRESSURE we GET `((dH)/(dT))_P =((dU)/(dT))_P + P((dV)/(dT))_P` `C=(dq)/(dT)` But at constant PRESSURE dq=dH Hence we get , `C_P=((dH)/(dT))_P` Thus HEAT capacity at constant pressure `(C_P)`is defined as the rate of change of enthalpy we respect to temperature at constant pressure |
