Question

We consider an isolated system made up of 2 moles of an ideal gas which can pass reversibly from a state A (PA, VA, TA = 300 K) to a state B (PB = 3PA, VB = VA / 3, TB) by a transformation which comprises two stages: it is first isochoric (constant volume), then isobaric (constant pressure).

1-Determine the work involved.

The ideal gas constant is R = 8.31 J / K.mol, and the internal energy of an ideal gas depends only on temperature.

2-how much heat is involved?

//

Entropy is conserved in a reversible process. true or false?
