When a puddle of water evaporates, does the water change into a new kind of matter

When water evaporates from its liquid form it changes into a gas. However, when water evaporates and becomes a gas it is no longer water (the name given to its liquid form) but is now considered water vapor. Water vapor is invisible and is lighter than air and for it to turn into water again must go through a process of condensation. 

Air pollution: “combustion results in gases such as nitrogen oxides, nitrogen dioxide and particulates. the main causes of air pollution include transport, domestic combustion and industrial processes. pollutants from these sources can cause problems in the immediate vicinity and a distance away.”
