please answer fast it's too urgent plsss dear plzzz reply fast ....

Answer 1

Answer:

conduction, convection, and radiation.

conduction :- the process in which heat is transferred from one place to another place without actual movement of particles of the medium.

ex :- when we heat one end of rod, the molecules at the hot get thermally agitated and transfer a part of their energy to the nearly molecules etc and so on. so the other end of the rod also gets heated by conduction.

convection :- the process in which heat is transferred from one place to another place by the actual movement of the particles of the medium.

ex :- sea breezes and trade winds.

radiation :- the process in which heat is transferred from one place to another place without help of any material medium is called radiation.

ex :- heat from the sun comes to earth by radiation.

any other doubts in physics then ask me...
