WebThe negative sign here indicates that the water lost energy. The assumption is that this energy lost by the water will be equal to the quantity of energy gained by the ice. So \(Q_{ice} = +7231.4 J\). Here, the positive sign indicates an energy gain. We can use this value with the equation to determine the heat of fusion of the ice. WebAdult Education. Basic Education.
