Question

find the work done required to compressed adiabatically one gram of air initially at NTP to half of its volume density of air at NTP= 0.001129 g/cm3 and Cp/Cv= 1.4

Answer 1

The adiabatic condition can be applied to determine the constant K . The work done by the gas can then be determined. If the final volume is less than the initial, then work is done on the gas and the work will be negative. and the final temperature can be obtained from the ideal gas law
