Question



A wooden spoon is dipped in a cup of ice-cream. Its other end

A.

becomes cold by the process of radiation

B.

becomes cold by the process of convection

C.

becomes cold by the process of conduction

D.

does not become cold

Correct option is D


The correct answer is does not become cold.
Heat Energy Transmission:
· Heat energy can transfer from one part of a body to another.
· This process is called heat energy transmission or simply heat transmission.
· There are three primary modes of heat transmission:
1. Conduction
2. Convection
3. Radiation
Conduction:
· Conduction is the process of heat transfer through solids, where heat is transmitted from the hotter end to the colder end.
· Materials that allow heat to pass through them easily are called conductors of heat.
· Examples: Aluminum, iron, copper.
· Materials like plastic and wood are poor conductors of heat because they do not allow heat to pass through them easily.
· Poor conductors are also referred to as insulators.
· A good conductor facilitates heat transmission, whereas a bad conductor resists heat transfer.
Example:
· A wooden spoon is a poor heat conductor.
· When a wooden spoon is dipped into a cup of ice cream, it does not become cold because it does not conduct heat efficiently.
