Answer:
True.
Explanation:
Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.
