Calculate the change in heat with correct mathematical sign that occurs as 1500.0g of water cools from steam at steam at 150C to ice at 150K. You may find the constants listed below helpful. Note that the enthalpies of fusion and vaporization are shown here in units of J/g, so the determination of those values involves the MASS of the water (not moles) and the enthalpy values (q=m AH). Ice: s=2.05J/KK Water: s=4.184J/KK Steam: s=2.00J/gK Hfu=+333.6J/g Happ=+2439J/g
