Question

The diagram shows a pot sitting on a gas stove burner. Which shows the order in which thermal energy is transferred by conduction? stove burner pan bottom of pan handle top of pan handle top of pan handle bottom of pan handle pan stove burner pan stove burner bottom of pan handle top of pan handle top of pan handle bottom of pan handle stove burner pan

Answer 1

Answer:

stove burner --> pan -- > bottom of pan handle --> top of pan handle

Explanation:

Conduction is one of the three methods of transfer of heat, and it occurs when the heat is transferred by contact/collisions between the molecules of two different mediums/objects (or also between molecules of different parts of the same object).

In this case, the transfer of heat by conduction occurs as follows:

- The stove burner is heated, and it is in contact with the pan --> the molecules of the stove burner move faster (they have more kinetic energy), so they transfer thermal energy (heat) by conduction to the molecules of the pan

- The pan is heated, and the same process occurs, but this time the heat is transferred to the bottom of the pan handle, which is attached to the pan

- Then, the bottom of the pan handle becomes hot, and by conduction heat is transferred also the part of the handle which is farther from the pan, so to the top part of the handle

Answer 2

Answer:

The question is not improper, But I will try to explain your doubt.

• The pot and part of stove are obviously in contact with each other. It is known as conduction

• The pot on gas stove burner, the air above the stove is heated and because  it is gas moves upwards, this is convection. The bottom of the pot and surface of the stove are not 100% flat. Thats why there will be little pockets of air underneath the pot,even if you place it on the stove.

If we heat up the stove as much as then it turns to red, this visible sign is known as radiation.

Therefore all the 3 kinds of heat transfer takes place
