Question

Solids transfer heat by

• A. conduction
• B. convection
• C. radiation
• D. all the three

Answer 1

The correct option is A

conduction

1. Heat flows in solids by conduction, where the particles are in contact with each other.
2. It is the transfer of heat through physical contact.
3. The particles of solid won’t travel along the body, they only vibrate at their respective positions and thus transfer of heat takes place by conduction.

Hence, option (A) is the correct answer.
