WebThermal conduction is a type of heat transfer that takes place between two systems which are in contact. The molecules inside these systems collide with each other for transferring the heat form one place to other. This type of heat conduction needs contact between two systems compulsorily for heat transfer to take place. WebIf two molecules collide, an energy transfer from the hot to the cold molecule occurs. The cumulative effect from all collisions results in a net flux of heat from the hot body to the colder body. We call this … slay internet
