A cylinder contains 0.250 mol of carbon dioxide (CO2) gas at a temperature of 27.0°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The cylinder is placed on a hot plate and 920 J of heat flows into the gas, thereby raising its temperature to 127.0°C. Assume that the CO2 may be treated as an ideal gas. (a) Draw a pV diagram of this process. (b) How much work is done by the gas in the process? (c) On what is this work done? (d) What is the change in internal energy of the gas? (e) How much work would have been done if the pressure had been 0.50 atm?
