Unformatted text preview: stop moving, we remove the weight and the piston goes up again. Does the gas return to its original state after adding and then removing the weight? We start by considering the first step of this process. Let A be the area of the piston. The gas pressure before the weight is dropped is P1 = m1g/A and with the weight it is P2 = m2g/A. Let us write the equation of state at the beginning and at the end: P1 V1 = (m1g/A) A h1 = R T1 P2 V2 = m...
