The question is presented as picture.

2. Relevant equations

What is the expression of this 'heat capacity C'?

The x-process is isothermal then C=nCΔT=0?

Please give me some ideas.

3. The attempt at a solution

set V1=V2, V3=V4, T1=T4, T2=T3, p1+p0=p2, p3-p0=p4

constant volume process:ΔU=n*Cv*(T2-T1)=Cv*V1*p0/R where p0=p2-p1

isothermal process:W=nRT1*ln(V3/V2)=nRT1*ln(p2/p3)

Then I can't go any further.
