A sample of ideal gas is placed inside a balloon at roomtemperature. The balloon is then put inside a freezer, where itdeflates without losing any of the gas inside it. The system is thegas inside the balloon.
I - Represent this process with a PV diagram.
II - Was the change in internal energy of the system, positive,negative, or zero? How do you know?
III - Was the work done by the atmosphere on the systempositive, negative, or zero? How do you know?
IV - Was the energy supplied to the system by heating positive,negative, or zero? How do you know?
V - Represent this process with a work-energy bar chart.
