Instruction: Answer the problems completely. Show your complete solution. Write legibly. A cylinder contains one mole of oxygen gas at a temperature of 27°C. 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 127°C. c. On what is this work done? Note: oxygen gas cp=29.17 J/mol-K cV=20.85J/mol-K nitrogengas cp=29.07 J/mol-K cV=20.76J/mol-K
