Five grams of nitrogen gas at an initial pressure of 3.0 atm and at 20∘c undergo an isobaric expansion until the volume has tripled.
a. What is the gas volume after the expansion?
b. What is the gas temperature after the 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? Finally, the gas is isothermally compressed until it returns to its initial volume.
d. What is the final gas pressure?
