Water vapor or aqueous vapor is the gas phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation. It is lighter than air and triggers convection currents that can lead to clouds.
Answer from wikipedia
Water vapour, damp or gas
Water that evaporates will rise and form clouds of water vapour.

Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.

Water vapour is most commonly know as a steam substance when water has started to boil and turn into a gas. Water vapour on a lake for example will rise into the atmosphere and start to condense into a cloud which will later on fall as a liquid (rain) when it is cool. This is called Changing State.
Water Vapour is considered as gas and since its particles are spread out it is light and therefore able to rise up into the clouds. As the clouds gather/collect water vapour it gets heavier. Cold air cools down the water vapour turning it back into water droplets and fall back to the ground.
Carbon dioxide and water vapor rise above the flame because they are products of combustion that have higher temperatures and lower densities than the surrounding air. This causes them to be buoyant and therefore they rise upwards above the flame.
It is called water vapour or simply vapour.
The molecular mass of water vapour is 18.01528
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
