* Melting is the process of a solid changing into a liquid.
* Freezing is the process of a liquid changing into a solid.
At the melting/freezing point, both processes happen simultaneously. Imagine ice melting in water:
* Some ice molecules are gaining energy and becoming liquid water.
* At the same time, some water molecules are losing energy and becoming solid ice.
The temperature at which this equilibrium occurs is the melting point (for the solid) and the freezing point (for the liquid).
Think of it this way: It's like a balance scale. At the melting/freezing point, the scale is perfectly balanced, with equal amounts of melting and freezing occurring.
