A quantity of 0.25 moles of ideal gas is enclosed in a cylinder, which is equipped with a piston on top of it. The piston has a mass of 7 kg and an area of 5 cm². The piston, which is free to move, is initially in mechanical equilibrium. The gas is heated, raising its temperature from 50 °C to 400 °C. As the gas is heated, the piston moves, keeping the pressure of the gas constant throughout the process. Calculate the work performed on the gas in this process. Show and explain your work.

Transcribed Image Text:A quantity of 0.25 moles of ideal gas is enclosed in a cylinder, which is equipped with a piston
on top of it. The piston has a mass of 7 kg and an area of 5 cm². The piston, which is free to
move, is initially in mechanical equilibrium. The gas is heated, raising its temperature from
50 °C to 400 °C. As the gas is heated, the piston moves, keeping the pressure of the gas constant
throughout the process. Calculate the work performed on the gas in this process. Show and
explain your work.
