1) The cp and the cv of air are, respectively, 0.24 and 0.17 Btu/Ibm.oR respectively. If 1000 Btu is added as heat to 20 Ibm of air in a nonflow, constant-pressure process, what is the final temperature? How much work is done by the gas if the initial temperature is 100 oF.

Air at 1 atm and 20 0C occupies an initial volume of 1000 cm3 in a cylinder. The air is confined by a piston which has a constant restraining force so that the gas pressure always remains constant. Heat is added to the air until its temperature reaches 260 0C. Calculate (a) the heat added (b) the work done by the gas, (c) the change in internal energy of the gas.

A cylinder if fitted with a floating piston oriented horizontally (the air is the system and by having a floating piston it maintains constant pressure). It contains 24.5 L of air at 25.0C and 1 bar pressure. The system is then heated to 250.0C. Air can be considered a diatomic gas and therefore would have a Cv = 5R/2, where R is the ideal gas constant. Also for gases Cp = Cv +R. How much work was done (in J)...
