To calculate the amount of energy required to melt the ice, we can use the formula:Energy Q = mass m heat of fusion L where:- Q is the energy required in Joules- m is the mass of the ice in grams- L is the heat of fusion of water in J/gGiven that the mass of the ice is 15 grams and the heat of fusion of water is 334 J/g, we can plug these values into the formula:Q = 15 g 334 J/gQ = 5010 JTherefore, 5010 Joules of energy are required to melt 15 grams of ice at 0C.
