One mole of a dilute gas initially has a pressure equal to 1.00 atm, and a volume equal to 26.0 L and an internal energy of 3.95 kJ. As the gas is slowly heated, the plot of its state on a PV diagram moves in a straight line to the final state. The gas now has a pressure equal to 4.00 atm, and a volume equal to 72.0 L, and an internal energy equal to 43.8 kJ. (a) Find the work done by the gas. kJ (b) Find the heat absorbed by the gas.
