824 gallons x approx 3.8 L/gallon = approx 3000 L (but you need to use a better factor and not estimate as I've done.
Then 3000 L has a mass of about 3000 g.
q = mass H2O x heat vaporiation = ?
Note: If you use 40.7 kJ/mol you must use mass H2O in mol(which means convert from grams to mols), and the answer will come out in kJ. Convert to MJ.
Old fashion steam locomotives operated by boiling water and using the steam to drive a piston that moved the train. How much energy ( in MJ) is required to turn 824 gallons of water at 100 C into steam? The heat of fusion for water is 6.01 kJ/mol and the heat of vaporization is 40.7 kJ/mol. The units are MJ.
