• C. Convection
• D. Radiation

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Evaporation

B

Conduction

C

Convection

There are three modes of heat transfer: conduction, convection, and radiation. Any energy exchange between bodies occurs through one of these modes or a combination of them. Conduction is the transfer of heat through solids, without moving the molecules in it. Convection uses the movement of molecules to transfer heat. Heat radiation is the transfer of heat energy without the help of a medium.
