An upright cylinder with a closed bottom is placed on a spring scale. The cylinder contains gas whose volume can be changed with the help of friction-free pistons that do not leak. Now, the piston is placed down. i) How much work was done by the surroundings to compress the gas a number of dV, while the spring scale drops by a distance of dy ii) If this device is only used to cause effects in gas, write down the work which is conducted
