What is work that must be done on the air in the cylinder

Reference no: EM13319107

A piston cylinder combination contains 2 kg of air at the ambient temperature of 25C and at the unknown ambient pressure. To provide a source of cooling on this hot Florida day, the piston is now pulled up until the air reaches a temperature of -100C. It can be assumed that the process is a polytropic one with. What is the work that must be done on the air in the cylinder to pull up the piston and produce the cold air? The piston must also do work on the air outside the cylinder, which remains at the ambient pressure. What is the expression for that work?
