Detailed explanation-1: -Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.
Detailed explanation-2: -Over time the metal will cool and the water will heat up. Eventually the two objects will have the same temperature. They are then said to be in thermal equilibrium with one another. During the intervening time the hot metal is transfering energy to the water.
Detailed explanation-3: -Conduction is the mode of transfer of heat in the form of particle vibration from hotter end to colder end of a body. The particles does not travel along the body, they only vibrate at their respective positions. Thus, it is the primary mode of heat transfer in solids like an iron rod.
Detailed explanation-4: -Conduction: The mode of heat transfer in solids where heat transfer takes place without the movement of medium particles is called conduction. For example: By heating one end of a metal rod we can feel the heat at the other end.
Detailed explanation-5: -The process by which heat is transferred from the hotter end to the colder end of an object is known as conduction. In convection, the heat transfer take place through transfer of molecules while radiation takes place through electromagnetic waves.
