Melting ice cubes illustrate the process of fusion. Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid. Substances in the molten state generally have reduced vis
To melt, the ice, the heat pump takes heat from the house to heat the outdoor coils. This reduces average heat pump efficiency. Supplemental Heat. As it gets colder outside, the heat pump provides less heat. Yet the house needs more heat to keep comfortable. At some outdoor temperature it will be too cold for the heat pump to provide all the heat the house needs.
