Carbon Dioxide CO2 is the bubbles that rise in the air.
rise because of it's density
The reason air rises is tempurture not dryness but as long as it is warm sure :)
My answer is, that there are air bubbles in the bottom of it, (WHEN ITS BOILING) Than those air bubbles rise to the top, & That's how hot water bubbles more than cold water.
due to heat, air expands and density decreases.air becomes lighter.lighter air rises up .
Warm air molecules are fast moving and therefore less dense than cold air molecules. Since cold air is more dense (more slowly moving) it sinks.
Well, warm air rises and cool air sinks! Your welcome! :) <3
Warm air rises. Cold air sinks.
Warm air is less dense than cold air so it rises.
Cold air is more dense than warm air. If flows beneath the warm air and forces it to rise.
rise because of it's density
cold air sinks as denser - warm air rises
Air is most likely to rise after a warm front passes over an area. Air rises as it gets warmer.
a difference in density
a deference in density
The reason air rises is tempurture not dryness but as long as it is warm sure :)
its bcuz air is enterning the bread..!! then it makes the bread rise and air bubbles or aka holes
