Answer

During compression pressure and temperature of gas increases. Molecular motion or disorderness increases with temperature. Hence, net work done requires for compression increases with temperature. Compression is carried out in multi-stages and intercooler is employed between two stages to bring down the gas temperature. Thus net work done is reduced. Moreover, work done can be minimised for isothermal compression.
