At a higher temperature, molecules have a higher energy and spread out faster.

At a higher temperature, molecules have a lower energy and spread out faster.

At a higher temperature, molecules have a higher energy and spread out slower.

At a lower temperature, molecules have a lower energy and spread out faster.

At a higher temperature, molecules have a lower energy and spread out slower.
