Why do bubbles form in boiling water?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

Does salt help water boil faster?
In fact, adding salt does the very opposite of making water boil faster. Instead, it makes it take longer for the water to boil! The salt actually increases the boiling point of the water, which is when the tendency for the water to evaporate is greater than the tendency for it to remain a liquid on a molecular level.
