Explanation:
When water molecules are placed on a heat source then these molecules will start to gain energy. Due to this there will be movement in the molecules of water.
As a result, more heat is provided to them farther away they tend to move from each other.
So, molecules at point B are farther away from molecules at point A. This means that these molecules have gained energy due to which they are moving at a faster rate.
Thus, we can conclude that molecules at point A are compared to the molecules at point B as follows.
