Q- The initial state of 1.00 mol of a gas is P1 = 6.00 atm, V1 = 5.00 L, and Eint 1 = 790 J, The gas is allowed to expand at constant pressure to a volume of 9.00 L. It is then cooled at constant volume until its pressure is 4.00 atm and its final state becomes P2 = 4.00 atm, V2 = 9.00 L, and Eint 2 = 890 J.
(a) Calculate the work done by the gas.
(b) Find the heat absorbed by the gas during this process.
