Passage / Comprehension

An ideal gas undergoes a single stage expansion against a constant opposing pressure from $(P_{1}, V_{1}, T)$ to $(P_{2}, V_{2}, T)$ .

The system in (Q.13) restored to its initial state by a single stage compression. What is the smallest mass ' m ' ' which must fall through the height ' $h$ ' to restore the system?

Options:

Answer:

Solution:

Work done on the system is $W = n RT (P_{1} / P_{2} - 1)$ .

This work equals potential energy $m^{'} g h$ .

So, $m^{'} = \frac{n RT}{g h} (\frac{P _{1}}{P _{2}} - 1)$ .
