Please give me your help so that I can understand this problem.. thank advanced

A cylinder of helium, with a movable piston, goes through a multi~step process: Start) 0.25 moles of He starts at 2 atm in equilibrium in a large pot of ice water. A. The gas cylinder is then placed into a large pot of boiling water and comes to equilibrium with the water while the cylinder is held at a constant volume. B. The gas cylinderis allowed to slowly change volume while in the boiling water unb'l the pressure is again 2 atm. C. The gas cylinderis then placed back in the ice water and comes to equilibrium while the cylinder is held at constant volume. D. The gas cylinderis then allowed to slowly change volume while held in the ice bath until the pressure is again 2 atm Determine the type of processes in this cycle, (A, B, C, and D). Draw these four processes on a single PV diagram, labeling point (1) as the initial state, point (2) as the state after the rst constant volume process, etc. (The processes will be connected.) What are the temperature, pressure, and volume of the gas at each of the points 1, 2, 3, and 4? Create a chart like the one below and ll out the energies using your results from above. Show that your results obey conservation of energy. Process AE' Q va A Total (Cycle)
