Question

A sample of ideal gas undergoes Isothermal expansion in a reversible manner from volume $V_{1}$ to volume $V_{2}$ .
The initial pressure is $P_{1}$ and the final pressure is $P_{2}$ . The same sample is then allowed to undergo reversible expansion under adiabatic conditions from volume $V_{1}$ to $V_{2}$ . The initial pressure being same but final pressure is $P_{2}$ .
If true 1 else 0
$P_{1} V_{1} = P_{2} V_{2}$

Solution

The correct option is A 1
As we know,
PV = nRT
so at constant temperature,
$P_{1} V_{1} = P_{2} V_{2}$
