Question

A vertical cylinder closed at the bottom has a smooth piston of mass $m$ and area $A$ with $\frac{m g}{A} = 0.5 P_{0}$ , where $P_{0} = 1 \times 1 0^{5}$ 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 gas is slowly heated to 400 K. The height of the piston becomes:

TestHub · Accepted Answer

The pressure stays at 1.5 P 0 ​ , so V ∝ T . Height = 30 × 300 400 ​ = 40 cm. C.
