In a close stationary system, 2 kg of argon is heated from 20 degree C to 120 degree C. Determine the amount of heat transfer when this is done during a (i) constant volume process; (ii) a constant pressure process A closed system contains 2kg of air undergoes an isothermal process from 600kPa and 100 degree C to 80kPa. Determine the internal energy change, the work done and the heat transfer during this process.
