If dQ , dU and dW are heat energy absorbed, change in internal energy and external work done respectively by a diamotic gas at constant pressure, then dW : dU : dQ is

Step-by-step solution

At constant pressure, Change in internal energy, dv = n _ v dT aligned & Heat, d = n C _ p dT & Work, dW = PdV = nRdT & dW : dU : d = nRdT : nC _ v dT : nC _ p dT & = nRdT : n 5 2 RdT : n 7 2 RdT & =2: 5: 7 aligned
