A cylinder contains an ideal gas at the temperature of 300 K and is closed by a movable piston. The gas, which is initially at a pressure of 3 atm occupying a volume of 30 L, expands isothermally to a volume of 80 L. The gas is then compressed isobarically, returning to its initial volume of 30 L. Calculate the work done by gas: a) in isothermal expansion; b) in isobaric compression, c) in the whole process; and d) Calculate...
