Why does boiling water create bubbles in a pot? Was the water not already taking up the space?
In: Physics
The bubbles are actually bubbles of steam. When the water at the bottom turns into steam it is now a bubble which then floats to the top as it is less dense than water.
The water was taking up space, it is just the volume of a gas is higher than the volume of it’s liquid form so it looks like a lot of bubble but it might be a tiny bit of the total amount of water in the bubble.
These bubbles actually cause the volume of the water in the pot to decrease so the space it is taking up decreases in accordance to the amount of water lost to steam formation
