Question: What do you think is inside the bubbles that form when the water boils? where did they come from?
The bubbles that form when water boils are pockets of water vapor, created when the heat applied to the water causes it to evaporate. As the water gets hotter, the pressure inside the bubbles increases until they eventually burst, releasing the water vapor into the air. The bubbles themselves are made up of a thin layer of water, which is held together by surface tension. The exact composition of the water vapor inside the bubbles can vary, depending on factors such as the temperature and pressure of the water, as well as any impurities that may be present. However, in general, the bubbles are primarily made up of water vapor and a small amount of air.
