ELI5: How can water evaporate normally in nature while having a 100°C boiling point?
gpt
The amount of energy that each molecule of water has is not equal, some have more and some have less than average.

If a molecule at the surface happens to have more energy than average it can fly off. This is evaporation. The hotter the liquid the more molecules will have enough energy to fly off, and so the greater the rate of evaporation.

When the water reaches its boiling point, so many molecules have lots of energy that they start to form a gas (water vapour) inside the liquid. Up to this point not enough molecules become gas, and so any bubbles that try to form get squeezed back into liquid.
