  • A vertical closed cylinder is separated into two parts by a frictionless piston of mass $m$ and of negligible thickness. The piston is free to move along the length of the cylinder. The length of the cylinder above the piston is $l_{1}$, and that below the piston is $l_{2}$, such that $l_{1}>l_{2}$. Each part of the cylinder contains $\mathrm{n}$ moles of an ideal gas at equal temperature T. If the piston is stationary, its mass, $m$, will be given by: $(\mathrm{R}$ is universal gas constant and $\mathrm{g}$ is the acceleration due to gravity)

  • There are two identical chambers, completely thermally insulated from surroundings. Both chambers have a partition wall dividing the chambers in two compartments. Compartment 1 is filled with an ideal gas and Compartment 3 is filled with a real gas. Compartments 2 and 4 are vacuum. A small hole (orifice) is made in the partition walls and the gases are allowed to expand in vacuum.

    Statement-1: No change in the temperature of the gas takes place when ideal gas expands in vacuum. However, the temperature of real gas goes down (cooling) when it expands in vacuum.

    Statement-2: The internal energy of an ideal gas is only kinetic. The internal energy of a real gas is kinetic as well as potential.
