Question

State three differences between water and air.

Answer 1

Solution

Hint : Water is an inorganic, transparent, tasteless, odourless, and nearly colourless chemical substance that is the primary component of the Earth's hydrosphere and all known living organisms' 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 $H_2O$ .

Complete Step By Step Answer:

Water	Air
Water is made up of hydrogen and oxygen, which are chemically combined in a constant mass ratio of 1:8	Nitrogen, oxygen, carbon dioxide, and water vapour are the primary components of air, and they are not chemically mixed.
Water has the same chemical makeup regardless of where it is acquired.	The composition of air varies depending on where you are. Because there is more water vapour in the air during the rainy season, it gets humid. Particular contaminants, such as sulphur dioxide and hydrogen sulphide, alter the composition of the gas in some areas.
The characteristics of water differ significantly from those of the elements from which it is made, namely hydrogen and oxygen.	Air, unlike its constituents, retains its unique characteristics.
When water is formed, it undergoes an energy shift	When air components are combined together, there is no energy change.
The precise formula $H_2O$ is used to describe a water molecule.	There is no chemical formula that can express air.

Note :
The atmosphere of Earth, often known as air, is the layer of gases that surrounds the planet and constitutes its planetary atmosphere and is held in place by gravity. The atmosphere of Earth supports life on Earth by producing pressure on the surface that allows liquid water to exist, absorbing ultraviolet solar radiation, warming the surface via heat retention (greenhouse effect), and minimising temperature extremes between day and night (the diurnal temperature variation).
