In the following indicator diagram, the net amount of work done will be:
Correct answer: B. Negative
- A. Positive
- B. Negative
- C. Zero
- D. Infinity
Explanation
The cyclic process 1 is clockwise whereas process 2 is anticlockwise. Clockwise area represents positive work and anticlockwise area represents negative work. Since negative area (2)>positive area (1), hence net work done is negative.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
