Question

A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254 kcal of heat is added to the gas, the volume is observed to increase slowly from 12.0 m³ to 16.2 m³. Part A Calculate the work done by the gas. Express your answer with the appropriate units. W = Part B Calculate the change in internal energy of the gas. Express your answer with the appropriate units. ?U =
