Melting point means the same as freezing point.It is the temperature at which a solid turns liquid,or a liquid turns solid.Water takes up less space as a liquid than as a solid.
This is because of the way the molecules stick together.In ice the molecules are grouped in rings.This takes up a lot of space.When the ice melts,the rings are broken.So the molecules can pack together more closely.
***notes down: temp.difference when drip in ice and after salt is added.
