## Homework Statement

Is it possible to calculate the work done heat transfer, and efficiency of an object in a thermodynamic system, given the Temperature vs Entropy graph?

Example:

## Homework Equations

∆U=Q-W

∆S=dQ/T

e=1-(Qc/Qh)

e=W/Qh

## The Attempt at a Solution

Since this is a T vs S diagram,i can understand how the product(area) will be heat.

Since it's a cyclic process, I can also understand how Q=W , since ∆U=0

Currently I'm thinking that the area inside the triangle will be W, which also corresponds to Q. However, I could barely find any documentation on this, which is why I wanted to confirm it.

As for efficiency, we are given two equations:

1-(Qc/Qh)

and

W/Qh

Would both of them be correct here, and would Qh and Qc be T2 and T1 respectively?

Thanks!
