Question

differences between the conduction and convection of heat​

Answer 1

Answer:

in conduction material mediumrequire and in convection do not any medium require

Answer 2

Answer:

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter.

Conduction :-

Conduction can be understood as the process, which enables direct transfer of heat through the matter, due to the difference in temperature, between adjacent parts of the object.

Convection :-

Convection implies the form of heat transfer, by real movement of matter, that occurs only in fluids.

Difference are as follows :-

1. Conduction is a process in which heat is transported between parts of a continuum, through direct physical contact. Convection is the principle, wherein heat is transmitted by currents in a fluid, i.e. liquid or gas.
2. Conduction shows, how heat is transferred between objects in direct contact, but Convection reflects how heat travels through liquids and gases.
3. Conduction usually occurs in solids, through molecular collision. Convection occurs in fluids by mass motion of molecules in the same direction.
4. The transfer of heat is through heated solid substance, in conduction, whereas in convection the heat energy is transmitted by way of intermediate medium.
