In an experiment to simulate conditions inside an automobileengine, 0.185 mol of air at 780 K and 3.00 * 106 Pa is contained in acylinder of volume 40.0 cm3. Then 645 J of heat is transferred to thecylinder. (a) If the volume of the cylinder is constant while the heat isadded, what is the final temperature of the air? Assume that the air isessentially nitrogen gas, and use the data in Table 19.1 even though thepressure is not low. Draw a pV-diagram for this process. (b) If insteadthe volume of the cylinder is allowed to increase while the pressure remainsconstant, repeat part (a).
