Purpose

To determine how temperature changes as ice is heated and becomes liquid water

Intuition
Have you ever sat and watched the ice melt in your cup in the summer? Or watched as you melted butter or chocolate while baking? Phase changes are not actually that interesting to watch, are they? Nothing seems to happen for a long time as you see both phases simultaneously together. Then when all of the solid material has finally melted, the liquid can finally heat up! 

Definitions

Melting Point, Calorimeter

Context & Theory
Depending on the temperature, most substances can exist as both a solid and a liquid. A substance in its liquid state has more thermal energy than it has in its solid state. The temperature at which a substance changes from a solid to a liquid is the melting point of the substance. The melting point is a characteristic property of a substance. Chemists often use the melting point to help identify or classify a substance.
