Question

What is conduction, convection, radiation?

Answer 1

CONVECTION:-CONVECTION IS THE TRANSFER OF HEAT BY ACTUAL MOVEMENT OF THE WARMED MATTER.CONVECTION IS PROCESS FOR GASES AND LIQUID TO TRANSFER HEAT.
CONDUCTION:-IT IS THE TRANSFER OF ENERGY THROUGH MATTER PARTICLE TO PARTICLE DISTRIBUTION OF HEAT FROM ATOM TO ATOM.
RADIATION:-ARE THE ELECTROMAGNETIC WAVES THAT DIRECTLY TRANSFER HEAT FROM SPACE,THE ENERGY TRAVELS THROUGH NOTINGNESS

Answer 2

Answer:

Conduction, Convection and Radiation are phenomenon of heat transfer or heat exchange. They are mainly distinguished due to the medium.

Conduction:

Conduction is a process in which heat is transfered from one point to another point in the same medium.

Convection:

Convection is a process in which heat is transfered from one medium to another medium. For example, heat transfer from air to a solid wall.

Radiation:

Radiation is a process in which heat is transfered from one point to another point regardless to the presence of any medium. For example, radiations coming from sun to earth.
