Passage / Comprehension

A sample of ideal gas is taken through the cyclic process shown in the figure. The temperature of the gas at state A is $T_{A} = 200$ K. At states B and C the temperature of the gas is the same.

Net work done by the gas in the process is

Options:

Answer:

Solution:

Net work in the cycle = area of the triangle $= \frac{1}{2} (Base) \times (Height)$ .

$= \frac{1}{2} \times (P_{B} - P_{A}) \times (3 V_{A} - V_{A}) = \frac{1}{2} \times 8 P_{A} \times 2 V_{A} = 8 P_{A} V_{A}$ .
