The pressure of a gas is maintained at 2.00 atm as it undergoes a quasi-static isobaric expansion from a volume of 3.50 L to a volume of 8.50 L. How much work is done by the gas to increase its volume?
When a gas undergoes a quasi-static isobaric compression, changing from a volume of 12.00 L to a volume of 5.50 L, 35 J of work from an external source are required. What is the pressure of the gas during its compression?
During the isobaric expansion from state to state represented in the diagram, the gas heats its surroundings with 599 J. What is the change in the gas’s internal energy?
