When you place a cooling pad on the forehead, physics is at work.
Body temperature is higher than the cooling pad.
Net heat flows from the body to the cooling pad.
The gel inside the pad evaporates.
Evaporation removes heat, so body temperature decreases.
Exam tip: Don’t just write “the cooling pad is cold.” Examiners want the physics chain: heat flow + evaporation = full marks.
AHA! Hot flows to cold, gel evaporates. Not by sight, but by INSIGHT!
