Examine a process whereby air at 300 K, 100 kPa is compressed in a piston/cylinder arrangement to 600 kPa. Assume the process is polytropic with exponent equal to 1.2 or 1.6. Find the work and heat transfer per unit mass of air in each case. Discuss the two cases and how they may be accomplished by insulating the cylinder or by providing heating or cooling.
