A cylinder with a moveable piston holds .20 lb of hydrogen initially in a volume of 1 cu ft at a tem-perature of 1300 F. Then the volume is expanded to 2.5 cu ft while the gas pressure remains constant.

a. What is the initial gas pressure?

b. What is the final gas pressure?

c. Find the final gas temperature.

d. How much heat has been transferred to the gas?

e. What mechanical WORK has been done on the piston by the gas?

f. What has been the change in internal energy of the gas?
