Question

What is colorless, odorless, and tasteless and cannot be felt?
a. Water
b. Air
c. Gas
d. Pollutants.

Answer 1

Hint: As we know that the environment of Earth, regularly known as air, is the layer of gases held by Earth's gravity that encompasses the planet and structures its planetary climate. The environment of Earth ensures life on Earth by making pressure taking into consideration fluid water to exist on the Earth's surface, retaining bright sun powered radiation, warming the surface through heat maintenance (nursery impact), and decreasing temperature limits among day and night (the diurnal temperature variety).

Complete answer:
Air is a drab, scentless and bland combination of gases comprising for the most part of nitrogen and oxygen. It is the piece of Earth's environment that people and any remaining creatures take to get the oxygen expected to support life.
The Earth's climate not just contains the air we inhale; it likewise holds billows of dampness that become the water we drink. Moreover, it shields us from meteors and unsafe sun based radiation and warms the Earth's surface by heat maintenance. Basically, the environment is an envelope that ensures all life on Earth.
The air may contain contaminants that begin from an assortment of sources like our enterprises and our vehicles, and can straightforwardly or by implication influence our wellbeing and the common habitat. These impacts might be capable of close to the wellsprings of air contamination and some air poisons might be moved significant distances by the breeze, even across political limits.

Option B is correct.

Note:
We need to know that by volume, dry air contains \[78.08\% \] nitrogen, \[20.95\% \] oxygen, \[0.93\% \] argon, \[0.04\% \] carbon dioxide, and modest quantities of other gases. Air additionally contains a variable measure of water fume, on normal around \[1\% \] a drift level, and \[0.4\% \] over the whole environment. Air organization, temperature, and barometrical pressing factors fluctuate with elevation. Inside the climate, air reasonable for use in photosynthesis by earthbound plants and breathing of earthly creatures is discovered uniquely in Earth's lower atmosphere.
