Conductores térmicos

The video tutorial explains how metal conducts heat efficiently due to its free-moving electrons, which transfer thermal energy quickly. It discusses the concept of thermal expansion, where heated atoms vibrate more, causing metals to expand. This principle is applied in structures like railroad tracks to accommodate expansion. Conversely, when metals cool, they contract, a process known as thermal shrinkage. The tutorial also covers how heat is transferred from a hot pan to the surrounding air, leading to cooling and contraction.
