Question

Explain the following
Convection , conduction, radiation of heat​

Answer 1

$\huge\mathcal\color{teal} Answer :-$

Convection :-

Convection is a process of heat transfer which occurs either in liquids or gases. In this process energy in the form of heat is transferred with the help of mass movement of energetic molecules from one point to another.

Conduction :-

Conduction is a process of heat transfer which occurs only in solids and is quite an efficient mechanism. It requires the transfer of energy in the form of heat by successive collisions of molecules of a solid. No mass movement takes place.

Radiation of heat :-

Radiation is a process of heat transfer which occurs mainly through a vacuum or a gaseous medium. In this mechanism electromagnetic waves carry energy from a hot body as it spread throughout a media.

Hope it helps !

Answer 2

Answer:

The above terms are related to the chapter heat .

Explanation:

Convection - it is the process in which heat transfers from liqiud to air . it requires a medium for transporting heat .

Conduction - it is the process in which heat transfers from solid to solid . it also requires a medium for transporting heat.

Radiation - it is the process in which heat transfer from air to air . it requires no medium .
