A rigid tank contains 5kg of water at 20 degrees Celsius. A gage on the tank reads 200kPa. Determine a) the volume of the tank, b) How much would the pressure in the tank increase if the temperature were increased to 50 degrees Celsius. c) A piston reduces (isentropically) the volume of the tank of half its initialvalue. How much id the pressure in the tank expected to increase? ( assume initial temp. 20 degrees)
