how does a solid become liquid - freezing
There is a special temperature for every substance called melting point. when a solids reaches the temperature of its melting point, it becomes a liquid. for water, the temperature needs to be a little over 0°C for you to melt.; what is actually happening is the atoms in the ice become excited by the rise in temperature, atoms start moving around faster and push away from neighbouring atoms. if their melting point were lower they also be liquids when the temperature is above 0°C. the reverse of the melting process is called freezing. freezing point, the temperature in which a liquid becomes solid. liquid water freezes and becomes solid ice when the molecules lose energy. at a liquid cools its particles slow down and come closer together.
