Definition

Freezing is the phase transition from the liquid state to the solid state. It occurs when a liquid's temperature is lowered below its freezing point.

5 Must Know Facts For Your Next Test

  1. The freezing point of a substance is the temperature at which it changes from a liquid to a solid under standard atmospheric pressure.
  2. During freezing, the kinetic energy of the molecules decreases, causing them to arrange into a fixed, orderly structure.
  3. Water has an unusual freezing point of 0ยฐC (32ยฐF) due to hydrogen bonding.
  4. Freezing is an exothermic process, meaning it releases heat into the surroundings.
  5. Supercooling can occur when a liquid remains in its liquid state below its normal freezing point without forming a solid.
