Question

Explain the term conduction,convection and radiation

Answer 1

the moment of heat energy from one molecule to another without changes in the relative position is called conduction. in convection heat is transferred from one point to another by a substance this method of transfer involves moment of heated molecules from one place to another. radiation is the process by which heat energy is emitted from a body it involves the flow of Radiant energy out of the body and through the air

Answer 2

HLO MATE HERE IS UR ANSWER.

❤. CONDUCTION ❤

⭐. The heat transfer from one place without the actual movement of the particles is called "conduction".

Ex: Heat transfer takes place from hot end of the rod to the other end by conduction.

❤. CONVECTION ❤

⭐. The heat transfer from one place to another place with the actual movement of particles is called "convection".

⭐. It is possible in only in fluids.

⭐. Convection can be natural or forced.

Ex: sea breeze , Land breeze , Trade wind.

❤. RADIATION ❤

⭐. Heat transfers from one place to another place without the help of the material of the medium is called "Radiation ".

⭐. It arises due to electro magnetic radiation emityed by a body by virtue of its temperature.

⭐. Radiation is the quickest mode of heat transmission .

Ex: Transfer of heat energy from the sun.
