Short Question Answers

Q1. Explain conduction, convection and radiation with examples.

Ans. Conduction: Conduction is the process in which heat is transmitted from one part of the body to the other without the actual movement of the particles.

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

Convention: It is the process in which heat is transferred from one point to another by the actual movement of the heated material particles.

Ex: Land and sea breezes and trade winds are due to convection.

Radiation: It is the process in which heat is transmitted from one place to another without any material medium.

Ex: Heat reaches the earth from the sun by the process of radiation. Heat radiations can pass through vacuum.
