What’s the difference between water boiling and it evaporating normally? Don’t both end up the same, ie. water turning into gas form?

Whenever you have a surface of liquid water, some water molecules will break free and fly away from the normal jostling around of molecules. That’s evaporation. And also, some water molecules that are flying around will collide with the surface and stick to it. If there are as many molecules colliding and sticking as there are breaking loose, then the overall evaporation stops. We call that 100% humidity, and it depends on how many molecules are flying around in the air.
Boiling is different – that happens when the temperature is too high for the water molecules to stick together at all. They are wiggling so much that it overcomes the stickiness that holds the whole blob together.
