rapidly from V, to V,.
The gas cools until the initial
pressure p, is restored.
The flame is turned off and
The gas is heated at constant
temperature until the volume
returns to V,
the piston is locked in place.

Expert Solution
Step 1
STEP 1:
a)
The P-V diagram of the given process can be represented as,
b)
Stage 1:
The process is a fast process; thus, it is an adiabatic process.
From the first law,
Here, Q, U, W represent the heat, the internal energy, and the work-done, respectively.
For an adiabatic process, the heat energy remains the same.
Thus,
Thus, the work changes into internal energy,
