A cylinder contains 3 moles of oxygen at a temperature of `27^(@)C`. The cylinder is provided with a frictionless piston which maintains a constant pressure of 1 atm on the gas. The gas is heated until its temperature rises to `127^(@)C`.
a. How much work is done by the gas in the process ?
b. What is the change in the internal energy of the gas ?
c. How much heat was supplied to the gas ?
For oxygen `C_(P) = 7.03 cal mol^(-1) .^(@)C^(-1)`.
