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 = nCv
t and not nCpt?/??
t 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????
