Did you know?
WebWe suppose that the energy released by the freezing of a d m mass of ice is used up by raising the temperature of both the already frozen ice ( m) and the remaining water ( M − m ): d m ⋅ H f = c i m ⋅ d T + ( M − m) c w ⋅ d T By rearranging we get a linear differential equation for m ( T): d m d T + c w − c i H f m = c w H f M WebJul 12, 2024 · As the water freezes, the temperature increases slightly due to the heat evolved during the freezing process and then holds constant at the melting point as the rest of the water freezes. Subsequently, the temperature of the ice decreases again as more heat is removed from the system. Figure 3.2.4: A Cooling Curve for Water.
