1. The problem statement, all variables and given/known data
a monatomic ideal gas(Cv=3/2R) undergoes an isothermal expansion at 300K, as the volume increased from 0.09m^3 to 0.36m^3. the final pressure is 100kPa. the change in the internal energy of the gas, in kJ is closest to
2. Relevant equations
3. The attempt at a solution
I think because it is an isothermal process the internal energy of an ideal gas depends only on the temperature. since the temperature remains the same wouldnt the internal energy be zero.

That is right.
