When you heat up water on the stove you can see tiny bubbles of oxygen form. THey rise to the surface long before the water begins to boil. Explain what causes these bubbles to form please

At first, the bubbles may be dissolved air coming out of solution as the water heats up. As the pan heats up, bubbles of water vapor form on the bottom of the pan and rise to the surface. This is called "film boiling". In neither case are the bubbles oxygen.

Well, cold water can simply hold more dissolved oxygen than hot water can. As the water heats up, it can't hold as much dissolved oxygen and so some of the oxygen bubbles away as a gas.
