Freezing
Definition
Freezing is the process in which a substance changes from a liquid to a solid state, usually as a result of temperature decrease.
Analogy
Think of freezing like turning off the dance music at a party. When the music (or heat) is on, all the party-goers (or molecules) are moving around freely and energetically (like in a liquid). But when you turn off the music (lower the temperature), everyone stops moving and stands still (becomes solid).
