Answer 1

A hand is burned when touching a pot handle

Answer 2

Answer: The correct answer is a hand is burned when touching a pot handle.

Explanation: There are 3 modes of 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.

From the given options,

A hand is burned when touching a pot handle is an example of conduction because there is direct contact between the hand and pot handle.
