I've always wondered where the bubbles of gas came from (assuming that's it). *Are* they gas bubbles?

The gas that forms in boiling water is still water but it is in its gaseous state. Remember that water can be solid (ice when temperature is 0C or below), liquid (when temperature is above 0C), and gas (steam - when its temperature is 100C or above). When you heat the water, its temperature rises. When the temperature reaches 100C, water starts to boil because it reaches its boiling point - where it changes from liquid to gas. That's why you see bubbles.
Also, please note that heating is not enough to break the bonds of H2O. It needs very high energy to do so. Hence, H2 and O2 are not formed during boiling of water.

The bubbles are flow; there is not any chemical reaction occurring while water boils. that's what boiling is - you realize, a liquid (water for this reason) being grew to become right into a gas (steam for this reason). quickly after boiling the (invisible) steam immediately condenses back into the seen water vapour which regularly gets suggested as steam.

When water turns to steam, it takes place at the bottom of the pan the water is in. A metal pan has small crevices or cracks where water molecules burst into steam. Teflon coated pans don't have those cracks and so the water doesn't bubble.

when we take water......it is in liquid state,ie it has some amount of heat(becoz if it does n't have heat,it wud be ice) .in the state of ice it is stiff.it does nt move much and it is hard.in a hotter state........water........it moves a little.when it is heated.......it turns into gas.remember more heat.........more it moves around.so when it turns 2 gas from liquid...........the bubbles occur.showing signs of the change.

O2 + H2 = H2O

yes its oxygen leaving the water (water is H20 , two hydrogen and one oxygen molecule). When you heat it, it breaks the reaction and oxygen is freed.

due to the temperature that presence to that..
