In a Carnot cycle, the isothermal expansion of an ideal gas takes place at 400K and the isothermal compression at 300K. During the expansion, 500 cal of heat energy are transferred to the gas. Determine (a) the heat rejected from the gas during isothermal compression, (b) the work done on the gas during the isothermal compression.
