Solids turn into liquids through temperature change. In the case of water, solid ice turns into liquid water because the temperature rises above 0 degrees Celcius. What is actually happening is the atoms in the ice become excited by the rise in temperature. They start moving around faster and push away from neighbouring atoms. The faster the atoms bounce about, the weaker they are held together.
Something that is really cool is that some solids can turn directly into gases, and gases can turn directly into solids without ever being a liquid! Carbon dioxide is a common example of this – dry ice is what we can the solid form.
Did you know when you put an ice cube in your drink its not the ice cube making your drink cold but rather your drink is ‘giving up’ its heat to the ice cube and causing it to melt. Heat energy always moves from a warm place to a cold place. Cool hey?
