An ideal monatomic gas is placed in a tall cylindrical jar of cross sectional area 0.095 m2. A frictionless 0.10 kg movable piston is placed vertically into the jar such that the piston’s weight is supported by the gas pressure in the jar. When the gas is heated (at constant pressure) from 25°C to 55°C, the piston rises 1.6 cm. How much heat was required for this process? Assume atmospheric pressure outside.
