As a Priority School, Goodland will have extra federal Title I funding to: 1  Add 250 hours of instruction to the school year-for the current year, we have done this by adding minutes to the normal Racine elementary school day.
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
Part 1: Heat of fusion. When water molecules are packed into a solid lattice they form bonds with their nearest neighbor molecules. To âmeltâ the solid (ice) requires the addition of energy. If the ice is at 0Â°C the addition of heat serves to break these bonds between the water molecules into a liquid state. Thus, when heat is added to the ice it melts rather than increasing in temperature. In this sense the addition of heat is not directly noticeable (by a rise in temperature) and is termed âlatentâ heat. Such a situation is characteristic also of liquid being turned into vapor.
