Consider the graph for cyclic process. The isothermal compression process among them is:
1
I
2
II
3
III

IV
Official Solution
Correct Option:
(3)
Concept: •Isothermal process: → rectangular hyperbola
•Compression: volume decreases (motion from right to left) Step 1: Identify isothermal curve
In a graph, isothermal process is represented by a curved (hyperbolic) path. Step 2: Check direction
Compression means volume decreases, so the path must move from right to left. Step 3: Analyze given processes •Process III: curved path with decreasing volume → isothermal compression
•Other processes represent expansion or different thermodynamic paths Conclusion
