Question
How is heat transmitted from one body to another?
Solution
There are three ways by which heat is transmitted from one body to another:
(i) Conduction: This is the phenomenon in which thermal energy is transferred from hotter part of the body to colder part or vice versa. There is no contact without any transference of material particles.
(ii) Convection: In this process, heat is transferred from one point to another point by actual movement of heated particles.
(iii) Radiation: In this process of transmission heat travels directly from one place to another place without heating any intervening media.
