Question

When one end of the rod is heated, the molecules at the hot end vibrate with higher amplitude and transmit the heat from one particle to the adjacent particle and so on. What is the process?

(a) Convection

(b) Conduction

(c) Radiation

(d) Transmittance

Answer 1

Correct choice is (b) Conduction

Explanation: In the above condition, heat is transmitted by the vibration of particles. Conduction is the process in which heat is transferred from hotter end to colder end without the actual motion of particles. Therefore, it is conduction.
