Hint: There are three types of transfer of heat from one object to other- conduction, convection, radiation. These are working in their state of matters.
Complete step by step answer:
Conduction: Conduction is a mode of heat transfer in solids because the molecules of solids bind tightly and heat transfer through one molecule to another molecule and this process is carried on in solids.
Convection: Convention is mode of heat transfer in fluids. And when fluid is heated the heat is moved away from the source.
Radiation: Radiation is the type of heat transfer in the forms of waves. This include electromagnetic wave, radio wave, X-rays
Air is not a good conductor in any form of energy. Air does not conduct with heat because their molecules are not continuous to transfer the heat from one molecule to another. Conduction is the mode of heat transfer in solids because their molecules are continuous. Conduction in air occurs when molecules of air collide with other molecules which is rare. Convection is a good mode of transfer of heat in air but it is less efficient than conduction.
So, the correct answer is “Option B”.
Note: There are three types of heat transfer conduction, convection and radiation. In accordance there speed radiation>conduction>convection.
