Question 8: A sample consisting of 1.00 mol Ar is expanded isothermally at 0°C from 22.4 dm³ to 44.8 dm³: (a) reversibly, (b) irreversibly against a constant external pressure equal to the final pressure of the gas, (c) freely (against zero external pressure). For the three processes, calculate q, w, AU and AH. Give all your answers to three significant figures.
