multiple choice question
when liquid water cools, but does not reach the point of freezing, the molecules
take up more space
pack closer together
move quicker
lose their hydrogen bonds
When liquid water cools (but doesn't freeze), its temperature decreases. As temperature is a measure of the average kinetic - energy of molecules, lower temperature means lower kinetic - energy. Molecules move more slowly and pack closer together. Water expands when it freezes due to the open - lattice structure formed by hydrogen bonds, but before freezing, cooling causes molecules to get closer.
