No change in the internal energy of the refrigerator
No energy being transferred
Nothing
Gas is compressed adiabatically in a cylinder with a cross-sectional area of 0.5 m2 by a piston moving 0.1 m as it does 150 J of work. How much pressure does the gas exert at the end of the piston's travel?

750 Pa
1500 Pa
3000 Pa
A gas expands and does 215 J of work on a piston. The gas exerts a pressure of 1230 Pa on the piston. What is the change in volume of the gas?
