Flag Thermal Physics> can any one tell me when to use Cp and Cv...
question mark

can any one tell me when to use Cp and Cv while calculating internal energy.
in adiabatic and polytropic process why do we say int. energy = nCvt and not nCpt?/??
(while we know that Cv is applied at const. vol. and Cp at const. press.)
why is then E=nCvdT applicable to all cases but nCpdT not????
