A monatomic ideal gas expands from point A to point B along the path shown in the drawing.
(a) Determine the work done by the gas.
(b) The temperature of the gas at point A is 198 K. What is its temperature at point B?
(c) How much heat has been added to the gas during the process? (This will be a negative number if heat has been removed from the gas.)
