11 Questions around this concept.
There are two identical chambers, completely thermally insulated from the surroundings. Both chambers have a partition wall dividing the chambers into 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 a vacuum.
Statement 1: No change in the temperature of the gas takes place when the ideal gas expands in a vacuum. However, the temperature of real gas goes down (cooling) when it expands in a 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.
N moles of an ideal gas are made to undergo a linear process $\mathrm{A}-\mathrm{B}$ shown on the $\mathrm{P}-\mathrm{V}$ diagram. The temperature will be maximum when volume is

Ideal gas - It is a hypothetical gas (which is not real gas), whose molecules occupy negligible space and have no interactions (Force of interaction is very less), and which consequently obeys the gas laws exactly.
So, the ideal gas does not exist in real, but for study we take some assumption to make the gas ideal and we can apply some laws which are only valid for ideal gases. These assumptions are -
