The Following Sets Of Values For Cv and Cp of A Gas Have Been Reported By Different Students. The Units Are Cal/gm-mole-K. Which Of These Sets Is Most Reliable?

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:

A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by 62^oC, the efficiency of the engine is doubled. The temperatures of the source and sink are:
