Based on its medium, the heat transfer process consists of three types and conduction is one of them. Conduction is the transfer of heat through an intermediate medium of substances, but only the energy of it without accompanied by the media transfer.
The heat flow speed is affected by the temperature difference between the delivery ends (ΔT), the area of the conducting cross section (A), the tip spacing having the temperature difference (L), and the type of conductor.Mathematically can be written with the following formula:H = Q / t = k. A. ΔT / L

FEW EXAMPLES IN DAY TO DAY LIFE ARE -

The heat from a hot coffee makes the cup itself hot  A metal spoon becomes hot from the boiling water inside the cup
You decide to touch the handle of the skillet after it has been on for several minutes, and now the handle is hot, too. This is because heat was conducted through the portion of the skillet in contact with the stovetop all throughout the rest of the skillet.
A shirt is placed on an ironing board to be ironed. Heat from the iron is conducted to the shirt, making it easy to iron out all those unsightly wrinkles and make the shirt look sharp.
