water vapor its boiled water if you collected the bubbles and cooled them off they would turn back into water

At 80 oC, small bubbles can be observed in water. These bubbles are air that was dissolved in the water at room temperature coming out of solution. Air becomes less soluble in water as the temperature goes up. If you continue to heat the water, bubbles form then collapse. The water on the bottom is heated to the point where it converts to vapour but the vapour cools and expands as it encounters the slightly cooler water just above it.
