Question

Water vapor is water as a: solid, liquid, or gas?

Answer 1

Water is an inorganic, clear, tasteless, odourless, and virtually colourless chemical liquid that is the primary component of the Earth's hydrosphere and all known living creatures' fluids (in which it acts as a solvent). Even though it contains no calories or organic nutrients, it is necessary for all known forms of life. Each of its molecules has one oxygen and two hydrogen atoms linked by covalent bonds, as indicated by its chemical formula ${{H}_{2}}O$ . The hydrogen atoms are 104.45 degrees apart from the oxygen atom. The liquid state of ${{H}_{2}}O$ at normal temperature and pressure is referred to as "water."

Complete answer:
The gaseous phase of water is known as water vapor. Within the hydrosphere, it is one type of water condition. Evaporation or boiling of liquid water, as well as sublimation of ice, can generate water vapour. Water vapour, like the majority of atmospheric components, is transparent. Water vapour is continually produced by evaporation and eliminated by condensation under normal atmospheric conditions. Its density is lower than that of most other air components, causing convection currents that can lead to clouds.
A water molecule is considered to have evaporated when it departs a surface and diffuses into the surrounding gas. Each individual water molecule absorbs or releases kinetic energy when it transitions between a more related (liquid) and a less associated (vapor/gas) state. Thermal energy is the aggregate measurement of this kinetic energy transfer, which happens only when the temperature of the water molecules differs. In a process known as evaporative cooling, liquid water that turns into water vapour carries a portion of the heat with it. How often molecules return to the surface is determined by the quantity of water vapour in the air.

Note:
It is notably prevalent in Earth's atmosphere, where it functions as the most potent greenhouse gas, stronger than other gases such as carbon dioxide and methane. It is a component of Earth's hydrosphere and hydrologic cycle. Since the industrial revolution, the use of water vapour as steam has been vital for cooking and as a key component in energy generation and transportation networks.
