Suppose that 30 g of highly compressed air `(C=0.177 cal//g. C^@)` is confined to a cylinder by a piston. Its volume is 2400 `cm^3` its pressure is `10xx10^5` Pa, and its temperature is `35^@C`. The air is expanded adiabatically until its volume is 24,000 `cm^3`. During the process, 4100 J of work is done by the air. What is its final temperature ?
