Physics - Heat & Thermo Question with Solution | TestHub

A vertical cylinder closed at the bottom has a smooth piston of mass $m$ and area $A$ with $\frac{mg}{A}=0.5P_0$, where $P_0=1\times 10^5$ N/$m^2$ is the atmospheric pressure. The piston encloses an ideal gas at 300 K and sits at a height of 30 cm. The walls conduct heat.

The pressure of the enclosed gas is:
