One mole of an ideal gas at $300 K$ is expanded isothermally from $1 L$ to $10 L$ volume. $Δ U$ for this process is (Use $R = 8.314 J K^{- 1} mol^{- 1}$ )NEET 2022 (Phase 2)

Options:

Answer:

Solution:

In an isothermal expansion or compression process, the temperature of system remains constant throughout the process. Since, for an ideal gas, $U$ depends only on temperature, it follows that the value of $Δ U$ is zero, during isothermal expansion of gas.
