6. An ideal gas expands isobarically from 3 atm from 400 to 600 ml. Heat then flows out of the gas at constant volume, and the pressure and temperature are allowed to decrease until the temperature reaches its original value. Calculate a) the total work done by the gas in the processes and b) the total heat flow to the gas.
