Sketch a PV diagram and find the work done by the gas during the following stages. (a) A gas is expanded from a volume of 1.0 L to 4.0 L at a constant pressure of 5.0 atm. (b) The gas is then cooled at constant volume until the pressure falls to 1.5 atm. (c) The gas is then compressed at a constant pressure of 1.5 atm from a volume of 4.0 L to 1.0 L. (Note: Be careful of signs.) (d) The gas is heated until its pressure increases from 1.5 atm to 5.0 atm at a constant volume. (e) Find the net work done during the complete cycle.Sketch a PV diagram of the process outlined in parts (a)–(d).

a)A gas undergoes two processes. In the first, the volume remains constant at 0.180 m3 and the pressure increases from 1.50×105 Pa to 6.50×105 Pa . The second process is a compression to a volume of 0.110 m3 at a constant pressure of 6.50×105 Pa . Find the total work done by the gas during both processes. b)The temperature of 0.160 mol of an ideal gas is held constant at 58.0 ∘C while its volume is reduced to a fraction of 30.0 % of its initial volume. The initial pressure of the gas is 1.22 atm . Determine the work done by the gas, what is the change in its internal energy, and Does the gas exchange heat with its surroundings? c)On a warm summer day, a large mass of air (atmospheric pressure 1.01×105Pa) is heated by the ground to a temperature of 27.0 ∘C and then begins to rise through the cooler surrounding air. Calculate the temperature of the air mass when it has risen to a level at which atmospheric pressure is only 8.60×104 Pa . Assume that air is an ideal gas, with γ=1.40. (This…

A cylinder of volume 0.320 m3 contains 10.5 mol of neon gas at 17.4°C. Assume neon behaves as an ideal gas.
