6. You get to your dive site and park the car. You put on your gear and get ready to enter the water. But first you check your scuba tank. It is filled to a pressure of about 25,000 kPa at 300 K. The volume of the tank is 25 L. You begin to wonder: If pressure remains constant, what would happen to the volume of gas in the tank if its temperature increased? (6 points) a. Which of the four thermal processes describes the temperature-volume relationship at constant pressure? (3 points)

b. Write the equation for this process. Hint: Think about the first law of thermodynamics. (3 points)
