- Homework Statement
- Calculate the temperatures at places 2, 4, A, B and C if you know:

It's an ideal diatomic gas

T3 = 4T1

T2 = Tb = T4

The axis connecting 1, B and 3 crosses zero.

- Relevant Equations
- pV = nRT

Laws of thermodynamics

I only know T3 = 4•T1

I was able to calculate the T2 = Tb = T4

I built four equations:

T2 = p2V1 / nR

T4 = p1V2 / nR

p1/T1 = p2/T2

V1/T2 = V2/4T1

I put them together and got T2 = 2T1

I can't figure out the temperatures of A and C. I tend to think Ta could equal Tc (then I would be able to calculate it), but I am not sure.
