- Homework Statement
- 2 moles of diatomic ideal gas goes through a cyclic process as shown below. From A to B (non-standard) , B to C (adiabatic), C to A (isothermal). Calculate work done by the gas in the process AB.

- Relevant Equations
- pV=nRT

So I've been digging this problem for quite some time, and still can't figure out a way to obtain work done in AB.

I do understand that work done in AB = area under the graph. However, I can't figure out how to obtain the volume at B. I can't use PV=nRT since I am unable to obtain the temperature at B. I am however able to obtain the temperature at A and C at 607.7K since it is a isothermal process. I tried summing change in internal energy =0, but can't proceed due to AB being a unstandard equation. What can I do in this case?
