1. 4 moles of an ideal gas have an initial temperature of 127 C. The temperature of the gas is kept constant and the volume is increases until the pressure drops to 40.0% of its original value.
(a) Draw a p V diagram for this process
(b) Calculate the work done by the gas.
(c) What is the change in internal energy of the gas?
(d) Calculate the heat added to the gas.
