Heat conduction in a metal rod | ingridscience.ca

The energy from the hot water makes the molecules of the metal rod move faster, which we can feel as the rod heating up. The heat spreads up the rod as the faster molecules at the end of the rod bump into adjacent molecules and give them energy too - so the middle of the rod (even though it was not touching the water) got warmer as well.
