A cylinder contains 0.200 mol of carbon dioxide (CO2) gas at a temperature of 30.0 ∘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 a 920 J of heat flows into the gas, thereby raising its temperature to 124 ∘C. Assume that the CO2 may be treated as an ideal gas.
What is the change in internal energy of the gas?
