What makes water boil?

Water boils when its vapor pressure equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid is the temperature at which its vapor pressure equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of water at sea level is 100 degrees Celsius (212 degrees Fahrenheit).

Here is a more detailed explanation of what happens when water boils:

1. Heat is added to the water. When you heat water, the water molecules gain energy and move faster.

2. The water molecules break away from each other. As the water molecules move faster, they start to break away from each other and form bubbles of water vapor.

3. The bubbles of water vapor rise to the surface. The bubbles of water vapor are less dense than the liquid water, so they rise to the surface.

4. The bubbles of water vapor burst. When the bubbles of water vapor reach the surface, they burst and release water vapor into the air.

5. The water vapor condenses into water droplets. The water vapor in the air then condenses into water droplets and forms clouds.

The boiling point of a liquid is affected by several factors, including the pressure of the surrounding gas, the presence of dissolved solids, and the purity of the liquid.
