About this resource...
Heat energy is constantly being transferred from one substance to another. Heat energy always moves from the hotter material to the colder material. When you hold an ice cube, it might feel like the coldness is creeping up your hand, but it’s actually the other way around—the heat of your body transfers to the ice cube, which results in the ice cube obtaining a higher temperature and eventually melting.Conduction is the most efficient form of heat transfer. In conduction, molecules of the warmer substance are moving faster than the molecules of the cooler substance. When the faster moving molecules collide with the slower moving molecules of the cooler substance, some of energy of the warmer substance is passed on. The cooler molecules that were directly collided with are moving faster, and when they collide with the surrounding cool molecules, they start moving faster too. Conduction is kind of like the game “telephone,” where the message is passed on by every individual in the circle.The speed of conduction depends on how different the temperatures of the two objects are, how far apart they are, and what type of are conducting the heat. For instance, metal is a far better conductor than Styrofoam. That’s why metal is used for cooking and Styrofoam is used for the disposable coffee cups.
