An ideal diatomic gas, without vibrations, loses heat Q in a process. The decrease in its internal energy is greater if the heat is lost in:

Answer:

Solution:

Isochoric: $Δ U = - Q$ . Isobaric: the gas contracts and

work is done on it, so $Δ U = - Q + W_{o n}$ , which is smaller in

magnitude. The decrease is greater in the isochoric process. A.
