* Conduction: Heat transfer by conduction happens when two objects at different temperatures are in direct contact. Heat energy flows from the hotter object to the colder object.
* Thermal Equilibrium: This is the state where both objects reach the same temperature. At this point, the net flow of heat energy between them stops.
Factors influencing the duration:
* Temperature difference: The larger the temperature difference, the faster the heat transfer, and the shorter the time to reach equilibrium.
* Thermal conductivity of materials: Materials with high thermal conductivity (like metals) transfer heat more quickly than materials with low thermal conductivity (like wood).
* Surface area of contact: A larger surface area in contact allows for more heat transfer, shortening the time.
* Mass of objects: Larger objects take longer to change temperature, so equilibrium takes longer.
Important Note: Even after reaching thermal equilibrium, there might still be a tiny amount of heat exchange, but it becomes negligible compared to the initial transfer.
