Question
2. A sample consisting of 2.00 mol He is expanded isothermally at 0° C fron 5.0 dm^3 to 20.0 dm^3 (i) reversibly, (ii) against a constant external pressure equal to the final pressure of the gas, and (iii) freely (against zero external pressure). For the three processes calculate q, w and ∆U.
