An ideal gas in a cylinder occupies a volume of 0.065 m3 at room temperature (T = 293 K). The gas is confined by a piston with a weight of 100 N and an area of 0.65 m2. The pressure above the piston is equal to one atmosphere (atm = 1.013x105 Pa). The piston is free to move up and down. 1) What is the magnitude of the net force on the piston? zero 50 N 100 N 2) Briefly explain your answer.
