👉 In physics, a "heatdrop" is a phenomenon where a small amount of heat (typically around 10°C or less) causes an object to cool down. This can happen due to the energy stored in the material being cooled and the movement of molecules within the material. For example, consider a rod that has been heated up slightly. When it's cooled down, the energy stored in the rod is released as heat drops, causing the rod to cool down. The temperature of the rod
