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 gas is heated until its temperature
increases to 127.0°C. Assume that the CO₂ may be treated
as an ideal gas.
