1) 0.05kg of carbon dioxide (molar mass 44 Kg/kmol) occupying a volume of 0.03m3 at 1.025 bar is compressed reversibly until the pressure is 6.15 bar. Calculate the final temperature the workdone on the co2 and the heat flow to or from the cylinder walls
(a) when the process is according to a law Pv= constant
(b) when the process is isothermal
(c) when the process takes place in a perfectly thermally insulated cylinder
Assume carbon dioxide to be a perfect gas and take α =1.3
2)Oxygen(molar mass 32 kg/kmol) is compressed reversibly and polytropically in a cylinder from 1.05 bar to 4.2 bar in such a way that one third of the work input is rejected as heat to the cylinder walls, calculate the final temperature of the oxygen. Assume oxygen to be a perfect gas an take cv= 0.649 KJ/kgK
