Question

How does temperatures affect the density of ocean water?

A) As temperatures decrease, molecules move further apart, making cold water less dense than the warm water.

B) As temperatures decrease, molecules move closer together, making cold water more dense then warm water.

C) As temperatures increase, molecules move further apart, making the cold water less dense than the warm water.

D) As temperatures increase, molecules move more closer together, making the warm water less dense than cold water.

Answer 1

As temperatures decrease, molecules move closer together, making cold water more dense than warm water.

Step-by-step explanation:

As temperatures increase, more energy is available to the molecules, which respond by moving at faster rates.

I took the test and it was right 100% :)

Answer 2

The correct answer is B. When temperature decreases the cold water is more dense due to molecules being stiffened together.
