A cylindrical pump contains a fixed number of gas molecules. The piston is free to move, but no gas can enter or leave the pump. The pump is also thermally isolated from the surroundings. Neglect friction between the piston and the cylinder walls. The piston is quickly pressed inward. a) Is the work done on the gas positive, negative or Explain your reasoning. Because it is quick there is little to no energy exchanged meening no work was done. A K zero? b) Is the heat transfer to the gas positive, negative or zero? Explain your reasoning. There is also I heat transfer. c) Did the internal energy of the gas increase, decrease or remain the same? Explain your reasoning. d) Does the temperature of the gas increase, decrease or remain the same? Explain your reasoning. e) Does the pressure of the gas increase, decrease or remain the same? Explain your reasoning. g) What type of process is this? f) Sketch a PV diagram representing this process. (Note: I want to know which axis is P and which is V so make sure to label them.)
