Consider a perfect gas contained in a cylinder and separated by a frictionless adiabatic piston into two

Question:

Consider a perfect gas contained in a cylinder and separated by a frictionless adiabatic piston into two sections A and B. All changes in B are isothermal; that is, a thermostat surrounds B to keep its temperature constant. There is 2.00mol of the gas molecules in each section. Initially TA =TB =300K, VA =VB =2.00dm3. Energy is supplied as heat to Section A and the piston moves to the right reversibly until the final volume of Section B is 1.00dm3. Calculate

(a) ΔSA and ΔSB,

(b) ΔAA and ΔAB,

(c) ΔGand ΔGB,

(d) ΔS of the total system and its surroundings. If numerical values cannot be obtained, indicate whether the values should be positive, negative, or zero or are indeterminate from the information given. (Assume CV,m =20JK−1mol−1.)
