Randall D. Knight — Work, Heat, and the First Law of Thermodynamics: Problem 57
5.0 g of nitrogen gas at 20°C and an initial pressure of 3.0 atm undergo an isobaric expansion until the volume has tripled. a. What are the gas volume and temperature after the expansion? b. How much heat energy is transferred to the gas to cause this expansion? The gas pressure is then decreased at constant volume until the original temperature is reached. c. What is the gas pressure after the decrease? d. What amount of heat energy is transferred from the gas as its pressure decreases? e. Show the total process on a pV diagram. Provide an appropriate scale on both axes.
