Concept introduction:
First Law of Thermodynamics states that the energy can transfer from one form to another form but neither be created nor be destroyed. Thus, in an isolated system, total energy is constant.
The mathematical expression is given by:
Where,
△U is change in internal energy
Q is heat
W is work done

Given Data:
This is a simple numeric question based on the formulae of First Law of Thermodynamics.
Formula given by first law of thermodynamics is:
Calculation:
From the First Law of Thermodynamics, we know that
For the Step 1 to 2:
Step 3 to 4:
Step 1 to 2 to 3 to 4 to 1: Since
Step 2 to 3:
For a series of steps, the total work done is the sum of work done for each step,
Step 4 to 1:
For the total process,
