The heat transfer is given by Q = m h If we are dealing with a conversion between the solid and liquid phase (e.g.,ice and water at 0 C), h is the latent heat of fusion, typically in units of k J k g. WebJan 25, 2024 · The emitted heat causes the temperature of the ice cubes to rise at first. However, if the ice starts to melt at a temperature of 0 °C (melting point), the temperature of the water-ice mixture does not increase any further. The temperature remains constant at 0 °C, even though heat is obviously being supplied by the heat lamp.
