Question

A tank of water is separated into two sections. Hot green water is placed on one side of the tank and clear cold water is placed on the other side. What would you predict will happen when the partition separating the tank is removed? Why? A) The water will cool without mixing as heat is transferred by conduction. B) You will see the green colored water move and mix with the cold water due to radiation. C) The clear water will move into the green water making it a lighter green by convection. Eliminate D) You will see the green colored water move and mix with the cold water due to convection.

Answer 1

D

Step-by-step explanation:

Answer 2

Answer: D) You will see the green colored water move and mix with the cold water due to convection.

Step-by-step 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 object.

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 direct transfer of energy through space.

The water molecules will definitely mix when the partition is removed due to 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.
