Instruction: Answer the problems completely. Show your complete solution. Write legibly.

1. A cylinder contains one mole of oxygen gas at a temperature of 27C. The cylinder is provided with a frictionless piston, which maintains a constant pressure at 1 atm on the gas. The gas heated until its temperature increases at 127C.

a. Draw a diagram representing the process in the pV-plane.

b. How much work is done by the gas on the process?

c. On what is this work done?

d. How much heat was supplied by the gas?

Note:

oxygen gas

cp=29.17 J/mol-K

cV=20.85J/mol-K

nitrogen gas

cp=29.07 J/mol-K

cV=20.76J/mol-K
