One mole of an ideal gas at 300 ~K is expanded isothermally from 1 ~L to 10 ~L volume. U for this process is (Use R =8.314 ~J ~K ⁻¹ ~mol ⁻¹ )

Step-by-step 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 ( U ) is zero, during isothermal expansion of gas.
