Because the water at 100 degrees centrigrade changes it's phase from liquid to gas. So the gas formed at the bottom of the container tries to escape through water present just above it.

The water is expanding from a liquid to a gas at 212 The air bubbles form as a result

Water as it reaches the boiling point starts
evaporating(changes from liquid to gaseous state)and this forms bubbles.

when the water starts boiling it changes its phase from liquid to vapour.thats y bubbles form in boiling water.

Water itself has some dissolved gases in it .The solubility of gases in liquids depend on the temperature.The solubility of gases decreases with increase in temperature. So as the water boils at 100deg C the gases in it come out as bubbles. So you will see bubbles in boiling water.

the water is turning to gas on account of the heat, more often when surrounded by hot water or the heat source on the bottom it's more suitable than the top which has air to cool it, so when it forms inside the water it rises to the top as bubbles.

The heat is causing the H20 molecules to move so rapidly that they bump into each other and break apart into their respective gasses. The gasses are lighter than the H20 and rise to the surface where they are then released aka bubbles.

because the water has passed its boiling point and is trying to change its physical state, (you know, like from a liquid to a gas)

There are so many gases dissolved in water. While boling they try to escape into air. This is what we see as air bubbles

When water is heated above its boiling point it gets vapourised.
