Ice cubes put in water will start to melt when they reach their melting point of 0 °C The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. Calculate the quantity of energy required to heat 1. The enthalpy of fusion is a function of the pressure at which that transformation takes place. K. However, our quantity is given in units of grams, not moles, so the first step is to convert grams to moles using the molar mass of H 2 O, which is 18. This is because sodium lowers the melting point of ice, meaning the solution must be colder before the ice will melt. Updated April 24, 2017. Hopefully, you see how the water heater BTU is related to this now!
