Answer:
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.
