Insulation

The video explains how thermal insulators, like wool and ceramic, help retain heat by blocking heat flow. It highlights that insulators not only keep objects warm but also prevent them from heating up, as seen in cool boxes. The presence of air pockets in materials enhances their insulating properties, making them effective in both hot and cold conditions.
