I know that temperature is given by the movement of the atoms in a substance. But why exactly it happens to form bubbles at the boiling point, which are wandering from the bottom to the top e.g in a pan? If they are made of oxygen , isn’t it at some time depleted? Shouldn’t the water then stop boiling?
In: Chemistry
The bubbles are steam.
The bottom is the hottest part of the pan. So the water reaches boiling point at the bottom and turns into steam. Its density is way smaller than liquid water so it raises to the top.
