Question

Water exists in all the states. Discuss.

Answer 1

Water is a transparent, tasteless, odorless, inorganic compound. The molecular formula of water is ${H_2}O$. Two hydrogen atoms covalently bond to one Oxygen atom to form a water molecule. Water exists in all the three states, solid, liquid and gas. It changes according to the temperature.

Complete step by step answer:
We are given to discuss water existing in all the states.
Water is an inorganic compound which is formed by hydrogen and oxygen. Hydrogen and oxygen covalently bond to form water. Hydrogen and Oxygen both are non-metals.
Water is also known as the universal solvent as most numbers of solutes are soluble in water. 70% of earth’s area is composed of water. Distilled water, the water with no added minerals or chemicals, is colorless, odorless and tasteless.
Water exists in Solid state as Ice, snow, in liquid state as water and in gaseous state as water vapour.
Water in solid state is fresh water found in the form of ice or snow in Polar Regions.
Water in liquid state is present in rivers, oceans, lakes, ponds etc.
Water in a gaseous state is present in the air as air moisture. Fog and mist are examples of water in a gaseous state.
Water in liquid state on cooling forms a solid at ${0^ \circ }C$ and on heating forms water vapour at ${100^ \circ }C$.

Note: Like water many other substances exist in all the three states. Some substances exist in only two states, (solid and gas), like camphor, naphthalene etc. Water can exist in all three states at a time at a temperature called triple point. Water is very essential for a human body as it carries the nutrients to all the cells in our body.
