For an ideal gas, the work done during reversible isothermal expansion can be calculated using the expression w = −nRT ln(Vf / Vi). A sample containing 1.0 mol of an ideal gas is expanded isothermally and reversibly to ten times its original volume in two separate experiments. The expansions are carried out at 300 K and at 600 K respectively. Choose the correct option.

- 1Work done at 600 K is 20 times the work done at 300 K.
- 2Work done at 300 K is twice the work done at 600 K.
- 3Work done at 600 K is twice the work done at 300 K.✓
- 4Work done is equal in both cases.
Correct answer
Work done at 600 K is twice the work done at 300 K.
