400 ml of air at standard conditions (25 C, 1 atm) is compressed adiabatically and reversibly while its volume is reduced by a factor of ten. Assume that this occurs in a piston/cylinder apparatus and that the ration of Cp/Cv for air is 1.4 throughout the entire process. a) If the cylinder has a bore (diameter) of 100 mm, what is the gap between the piston and cylinder head at the end of the compression process? b) What is the final temperature? c) What is the final pressure? d) What heat transfer occurs during this process? e) What work transfer occurs during this process?
