(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A monatomic gas has V1 P1 and T1 (volume pressure and temp) at state 1

The gas then goes through the following process

adiabatic expansion to stage 2 (exapands to twice its volume)

isovolumetric heating so it gets back to T1; stage 3

isothermal compression back to intial state

2. Relevant equations

- Sketch on pV diagram? (done this)

- derive expressions for P2 and P3 (in terms of p1 and [tex]\gamma[/tex]) ?

- derive expressions for T2 and T3 (in terms of T1 and [tex]\gamma[/tex])?

- expression for net work done in 1 cycle?

- is this an engine or refridgerator?

3. The attempt at a solution

i've managed to find

P2 = P1 / (2^[tex]\gamma[/tex])

and that [tex]\gamma[/tex] = 5/3

The 2 questions in bold are the ones really stressing me out; if someone could please put up some solutions or just point me in the right way that would be great :)

Thanks
