WebNoun (wikipedia freezing) (uncountable, physics, chemistry) The change in state of a substance from liquid to solid by cooling to a critically low temperature. * 1829 , James … WebThe melting and freezing points are named so by associating them with the two different states of matter. Can explain it in the following manner, the same two states, i.e., solid and liquid, are involved in the change of state at melting (solid to liquid) and freezing point (liquid to solid). Therefore, both of them are going to have exact values. WebMelting - solid to liquid. When a solid is heated, its particles gain enough energy to overcome the bonding forces holding them firmly in place. They start to move about, but stay close to their neighbouring particles, rolling around each other. This particle movement allows the substance to flow and form a liquid. churchfields recycling
