In An Isochoric Change, There Is No:

The internal energy of an ideal gas depends on:

Heat added to a system is equal to:

In the condensation of a gas the mean KE (K) and potential energy (U) of molecules change;

 thus:

When 110 J of heat is added to a gaseous system, internal energy increases by 40 J; the amount of work done is:

A gas has:

Mean kinetic energy per gram molecule for diatomic gas is:

Molar specific heat at constant volume C_v for a mono-atomic gas is:

C­_p >C_v, as in the case of C_p:

The following sets of values for C_v and C_p of a gas have been reported by different students. The units are cal/gm-mole-K. Which of these sets is most reliable?
