coal is a fossil fuel that burns without giving water vapour.
When hydrogen burns, water vapor (H2O) is produced as a byproduct.
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
Condensation of water vapor is a physical change, not a chemical change. It involves the transition of water vapor into liquid water due to a decrease in temperature, without any change in the chemical composition of water molecules.
Water vapor is in the gaseous state, not the liquid state. It is formed when water evaporates into the air as a gas.
You could use it like this...... I like to use water vapour. sorry it is not much of a sentence.......

giving out excess of water as water vapour

water vapour
Pure hydrogen gas burns without producing water vapor because it combines with oxygen to form only water. Other fuels like methane or gasoline produce water vapor when they burn because they contain hydrogen atoms that combine with oxygen from the air.

Hydrogen is abundant and, burns giving off only Water Vapor.
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.
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
