Question
An ideal gas undergoes this method:
In a p V diagram point 1 starts at (V1,P1) moves to (V1, P2) then to (V2,P2) then (V2,P1) then ends back at (V1,P1) Where P2>P1 and V2>V1
This is just an ideal Carnot cycle engine where for case the expression for heat expelled for the section from (V2,P2) to (V2,P1) equals (f/2)*V2(P1-P2) Ok so here is the question
A) calculate the Change in internal energy for Gas
B) calculate the net work done on Gas
C) calculate the net heat added to Gas
D) calculate the entropy change of Gas
