Transcribed Image Text:E2A.4(a) A sample consisting of 1.00 mol Ar is expanded isothermally at
20°C from 10.0 dm’ to 30.0 dm' (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 AU.
