Science how does solid become a liquidación

When you get a solid hot, the molecules bump around faster and harder until they start breaking apart and moving around each other; that's when a solid melts and becomes a liquid. However, in a liquid, the molecules still pull on each other enough to stay bunched together (that’s why a drop of water on a table is round, and doesn’t spread out all over).

Freezing

The purpose of this lab was determining the molecular weight of an unknown solid organic compound by freezing point depression. In order to do so, one has to first, freeze cyclohxane, by putting it in ice cold water, and see what the constant temperature comes out as. Then, one has to freeze .
