An ideal gas is taken around ABCA as shown in the P-V diagram. The work done during cycle is:
Correct answer: A. 2PV
- A. 2PV
- B. 1/2PV
- C. PV
- D. Zero
Explanation
Work done= Area enclosed by triangle ABC = 1/2AC x BC= 1/2 x (3V-V) x (3P-P)=2PV

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.
