What happens to the average kinetic energy of water molecules as water freezes?

Feb 7, 2016

When water freezes, the temperature decreases and therefore, the average kinetic energy will decrease as well.

Explanation:

The average kinetic energy $K . E {.}_{a v .}$ is measured by:

$K . E {.}_{a v .} = \frac{3}{2} R T$

which means that the average kinetic energy is directly proportional to the temperature .

When water freezes, the temperature decreases and therefore, the average kinetic energy will decrease as well.
