In an isothermal expansion of an ideal gas, select the wrong statement.

View answer and explanation

Correct option: D

The work done by the gas is equal to the change in its internal energy

Option D (The work done by the gas is equal to the change in its internal energy) is the wrong statement because in an isothermal process, the change in internal energy is zero, and the work done is equal to the heat supplied.
