100 cubic meters of carbon dioxide initially at 150 C and 50 bar is to be isotermally compressed in a frictionless piston and cylinder device to a final pressure of 300 bar. Calculate:

i. The volum eof the compressed gas
ii. The work done to compress the gas
iii. teh heat flow on compression assuming carbon dioxide

obeying the principles of corresponding states.

Are you acquainted with some of the formulas that relate the volume to pressure and temperature, and those that relate force, to work?  Can you copy those formulas down, and try to plug in some values, so we can begin to help you, help yourself, so that you'll be better off the next time these sorts of questions come up?
