So we can say Conduction is equal to Direct contact. When we heat the Iron at one side the other side automatically gets heated because the molecules present in it travels to another side and heated that area too. In Conduction, the heat or energy is transferred by a direct contact like when any heated object you touch with your hand the conduction process take place. There is a total of 3 Modes of Heat transfer which is: Now further it has been categorized in the 3 types which are: Modes of Heat Treatment: The extreme or moderate or low heated object leaves the heat at the room temperature. So the temperature of the air is less than the temperature of cooked food, it (temp) starts emitting to surrounding and this process goes on till both come in the normal temperature. So what we do for, we are keeping to an open environment or near to fan. Initially, we provide heat and after preparing food we are trying to extract heat to eat the cooked food. The heat transfer takes place from the high-temperature body to low-temperature body. So Heat is the form of energy which is associated with the motion of molecules or atoms. Before going to study the heat transfer in details lets have an overview on Heat first.
