Molecules in a gas have lots of energy and spread out even more than molecules in a liquid. Warm water has more energy than cold water, which means that molecules in warm water move faster than molecules in cold water. If the atoms of an object are moving fast, the temperature would be High
Low
Medium
Unknown

High

Explanation:

The answer to this question has been hinted in the question;

molecules in warm water move faster than molecules in cold water

This means that the relationship between temperature and movement of atoms is as follows;

At higher temperatures, atoms possess more energy and due to this they are able to move at high velocity (really fast).

On the other hand, lower temperatures means that the atoms possess less energy and due to this they move with a lower velocity.

law of conservation of matter

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
