Hooray! There’s no school today. This is because the rain that was left on the roads and trees last night froze. What must have
occurred for this happen? A)The water particles must have lost energy B)The water particles must have gained energy.EliminateC)The water particles must have begun to move faster. D)The kinetic energy of the water particles must have increased.
The correct answer is A. The water particles must have lost energy.
Explanation:
The freezing point is reached in a solution when the kinetic energy of the molecules becomes smaller as the temperature decreases; the increase of the intermolecular forces of attraction and the decrease of the kinetic energy are the causes of which the liquids crystallize. Solutions always freeze at a lower temperature than pure solvent. The freezing temperature of pure water is 0 ° C.
