Why Water Boils Faster on a Mountain but Cooks Food Slower

Why does water boil faster on a mountain yet make weak tea and slow-cooked eggs? Boiling is not a fixed temperature; it is the moment vapour inside a bubble can push back against the air pressing down. You will learn how boiling differs from evaporation, why vapour pressure climbs so steeply with temperature, and why thinner mountain air lowers the boiling point to around ninety degrees at three thousand metres and about seventy on the highest peaks. The video explains why cooler boiling water cooks food more slowly, how a pressure cooker pushes boiling to around a hundred and twenty degrees, and how warm water can boil with no heat at all.
