The $CO _{2}$ content by volume, in the atmospheric air is about

evs atmosphere- wind weather, climate and adaptation of animals to different climates climate and weather weather, climate and adaptations of animals to climate

  1. 3.34%

  2. 4%

  3. 0.0314%

  4. 2.1%.

Show answer
Correct Option: C
Explanation:

The carbon dioxide present in the atmosphere is generally the result of respiration by animals during the day and the emissions by various vehicles, industries and machines. All these activities account for a total of approximately 0.04% CO2 in the atmospheric air.

So, the correct answer is '0.0314%'.

Ozone is formed in stratosphere by action of ultravoilet radiations on oxygen.

  1. True

  2. False

  3. Either

  4. Neither

Show answer
Correct Option: A
Explanation:
Ozone (O3) molecule is made up of three oxygen atoms. It is formed in the stratosphere when single oxygen atom combines with a molecule of oxygen i.e. when [O] combines with O2. Oxygen molecule consisting of two oxygen atoms splits into atomic oxygen in the presence of ultraviolet radiation. The atomic oxygen then combines with another molecule of oxygen to form ozone.
The reactions are as follows:
      UV light
O2 ---------------> [O] + [O]
[O] + O2 ---------->O3
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.

PAN is

evs atmosphere- wind weather, climate and adaptation of animals to different climates climate and weather weather, climate and adaptations of animals to climate

  1. poisonous american nuisance

  2. primary air pollutant

  3. photochemical oxidant

  4. particulate atmospheric nitrogen compound

Show answer
Correct Option: D
Explanation:

PAN (Peroxyacytyl nitrate) is a toxic chemical that is an important component of smog.PAN molecules are generally composed of carbon, hydrogen, oxygen, and nitrogen atoms.

So the correct answer will be 'PARTICULATE ATMOSPHERIC NITROGEN COMPOUND'.
