MCQ
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
- ✓Statement $-1$ is false and Statement $-2$ is true
- BStatement $-1$ and Statement $-2$ both are true. Statement $-2$ is the correct explanation of Statement $-1$
- CStatement $-1$ is true and Statemcnt $-2$ is false
