An ideal gas at temperature T0 is slowly com- pressed at constant pressure of 2 atm from a volume of 10 liters to a volume of 2 liters. Then the volume of the gas is held constant while heat is added, raising the gas tempera- ture back to T0. Calculate the work done ON the gas. 1 atm = 1.0×105 Pascals and 1 liter = 0.001 m3. Calculate the heat flow INTO the gas.
