What causes bubbles in water?

As the glass filled with water sits out for a few hours, its temperature rises slightly (water gets warmer), which causes the dissolved gases in it to come out of the water and form bubbles along the inside of the glass.

What happens if you put noodles in before water boils?
Explanation or Science of Boiling Water: Pasta added to water before it starts to boil gets a heat start on mushiness. Pasta quickly begins to break down in tepid water as the starch dissolves.
