The process of transferring heat through direct contact between materials is called conduction. This heat transfer occurs when fast-moving particles in a warmer material collide with slower particles in a cooler material, leading to energy transfer. Conduction is particularly efficient in solids, where particles are closely packed, allowing for effective energy transfer. An everyday example of conduction is touching a hot stove, where heat moves from the stove to your hand, which may cause burns if not careful.
