Question: In an experiment to simulate conditions inside an automobile engine, 0.185 mol of air at a temperature of 780 K and a pressure of 3.00

In an experiment to simulate conditions inside an automobile engine, 0.185 mol of air at a temperature of 780 K and a pressure of 3.00 X 106 Pa is contained in a cylinder of volume 40.0 cm3. Then 645 J of heat is transferred to the cylinder.
(a) If the volume of the cylinder is constant while the heat is added, what is the final temperature of the air'? Assume that the air is essentially nitrogen gas, and use the data in Table 19.1 even though the pressure is not low. Draw a pV-diagram for this process.
(b) If instead the volume of the cylinder is allowed to increase while the pressure remains constant, find the final temperature of the air. Draw a pV-diagram for this process.
