Question

what happens to ocean water molecules when they become colder? they move more rapidly they spread apart they become less dense they pack together more tightly

Explanation:

When water cools, its molecules slow down and pack together more tightly due to decreased kinetic energy. This is a fundamental property of matter related to temperature - energy relationship. As temperature decreases, molecular motion decreases and intermolecular forces pull molecules closer.

Answer:

They pack together more tightly
