Question

Explain three modes of transmission of heat; i.e., conduction, convection and radiation, with the help of their applications.

Answer 1

transfer of heat through solid conduction
transfer heat through liquid convection
transfer of heat without medium radiation

Answer 2

hey mate

conduction-it is the method in which heat is transferred from hot body to cold body withouth the actual flow of matter it requires a medium to flow

application-when we heat an iron rod then it starts heating from one side and soon it is heated up fully


2)Convection-it is the method in whic heat is transferred with actual flow of matter it also requires a medium to flow

eg-heat when we heat water the cold water after heating becomes light and hot and goes up and the cold water takes its place so here is actuall flow of matter


3)Radiation-it is the method which does not requires any medium to flow and it travels with the speed up light

eg-heat from the sun went to earth this is an exampleof radiation
