Question

how to explain when water freezes?
when water molecules are squeezed together by high pressure and stick together?
or
they slow down and begin to bond together

Answer 1

When temperature decreases, molecules slow down.

With water, when the molecules slow down, it freezes.

Answer 2

..they slow down and the intermolecular forces between the molecules become more significant, they form a network of hydrogen bonds, a more structured phase, which decreases it's density by increasing the distance between molecules.

Answer 3

Thank you, for your very detailed explanation.
I did try to play it very simple.

Answer 4

It is the last choice.
