Here's how it works:
* Heat energy is transferred through the vibration of atoms and molecules within a material.
* When a hotter object touches a cooler object, the faster-moving particles in the hotter object collide with the slower-moving particles in the cooler object.
* This collision causes the slower-moving particles to speed up, increasing their kinetic energy and transferring heat from the hotter object to the cooler object.
Examples of conduction:
* Heating a pan on a stove: Heat from the stove burner is transferred to the pan by conduction, and then to the food inside the pan.
* Holding a hot cup of coffee: Heat from the coffee is transferred to your hand by conduction.
* Touching a cold metal surface: Heat is transferred from your hand to the metal surface by conduction.
Conduction is most efficient in materials with tightly packed atoms and molecules, such as metals.
