Web1 jan. 2024 · When you touch a hot stove, the heat from the burner is transferred to your hand. If you hold a metal spoon in your hand and touch the spoon to the burner, your hand will eventually get hot because the heat conducts through the spoon. However, if you wear an oven mitt (insulation), much less of that heat energy will make it to your hand. WebIn conduction, heat is transferred from a hot temperature location to a cold temperature location. The transfer of heat will continue as long as there is a difference in temperature between the two locations. Once the two locations have reached the same temperature, thermal equilibrium is established and the heat transfer stops.
