Question

what are the modes of heat transfer ? explain them .

Answer 1

There are three modes of heat transfer 1. conduction 2. convection, 3. radiation.  

Conduction is the transfer of heat through solids or stationery fluids.

Convection uses the movement of fluids to transfer heat.

Radiation does not require a medium for transferring heat, this mode uses the electromagnetic radiation emitted by an object for exchanging heat

Hope its helpfull

brainliest please

Answer 2

There are three modes of heat transfer: conduction, convection, andradiation. Any energy exchange between bodies occurs through one of these modes or a combination of them. Conduction is the transfer of heat through solids or stationery fluids.Convection uses the movement of fluids to transfer heat
