If the magnet loses its superconducting properties, all of the liquid helium could suddenly turn to a gas. Use the ideal gas law, PV = nRT, to determine how many liters of Helium gas would be formed from 1 L of Helium liquid at 1 atm pressure and 25C. 1 L of liquid Helium contains 31.25 mol Helium. (The gas constant is 0.0821 L atm/mol K.) Show your work. (3 points)
