Answer: D) You will see the green-colored water move and mix with the cold water due to convection.
Explanation:
There are three ways in which there is heat transfer.
Conduction: This type of heat transfer happens when there is direct contact between the two objects.
Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).
Radiation: This type of heat transfer happens when there is a direct transfer of energy through space.
The water molecules will definitely mix when the partition is removed due to the diffusion of particles.
As the green water is hot, it is less dense and thus can move faster and will rise as compared to clear cold water and will transfer heat to colder particles.
