# A cylinder contains 0.250 mol of carbon dioxide (CO2) gas

##
A cylinder contains 0.250 mol of carbon dioxide (CO2) gas at a temperature of 27.0oC. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The gas is heated until its temperature increases to 127.0oC. Assume that the CO2 may he treated as an ideal gas.

(a) Draw a pV-diagram for this process.

(b) How much work is done by the gas in this process?

(c) On what is this work done?

(d) What is the change in internal energy of the gas?

(e) How much heat was supplied to the gas?

(f) How much work would have been done if the pressure had been 0.50 atm?
