Air Pollution Questions

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

Incineration of plastics causes:

  1. nitrogen emission

  2. sulfur emission

  3. carbon emission

  4. all of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. The $CO _2$ is produced when plastics are incinerated. The plastics are petroleum oil and gas derived products  and are generally treated as non-renewable.

Which of the following can be related to both soil and air pollution?

  1. Intensive farming

  2. Acid rain

  3. Leaching

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acid rain is the secondary effect of air pollution. The gases like sulphur dioxide and nitrogen oxide when in high concentration in the air, mix with the air moisture in clouds and form sulphuric and nitric acids. These acids come down to the earth in the form of acid rain-causing much damage to the living organism and buildings. Acid rain pollutes water and soil both. When the rain droplets get mixed with nitrogen and sulfur oxide it causes acid rain. this acid rain when fall on earth reacts with soil because of chemicals present in acid rain, the fertility of particular area gets affected.

Thus, the correct answer is option B.

Multiple choice geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

Particulate matter is released in the air mainly from ___________.

  1. Burning fossil fuels

  2. Dumping glass and garbage on land

  3. Hot water from factories

  4. Heavy metal effluents
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fossil fuels include coal, petroleum, natural gas etc. These are used to generate energy for transportation cooking and many other. Such actions release particulate matter which includes suspended chemical compounds like oxides of sulphur and nitrogen and dangerous gases like carbonmonooxides.

Multiple choice physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

The equipment installed in power plants to reduce air pollution due to smoke is

  1. Induced draft fans

  2. De-super heaters

  3. Electrostatic precipitators

  4. Re-heaters
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Electrostatic precipitators device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates and used to reduce air pollution due to smoke in power plants.

All of the following is the method to control air pollution except

  1. Use of CNG gas

  2. Use of LPG gas

  3. Aforestation

  4. Use of cycle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The domestic cooking gas cylinder contains Liquid petroleum gas.
  • Its composition is propane or butane or a mixture of both, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.
  • Use of LPG is not a method to control air pollution because Inhaling of LPG vapour can cause irritation in nose and throat, headache and nausea, vomiting, dizziness and loss of consciousness.
  • Hence Use of LPG gas is not a method to control air pollution.
  • So, the correct answer is 'Use of LPG gas'.

Multiple choice evs - i life is precious road safety and pollution pollution of natural resources air pollution and its effects

In metropolitan cities, the automobiles cause air pollution.

  1. $80\%$
  2. $60\%$
  3. $50\%$
  4. $100\%$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Most of the automobiles have an environmental impact up to 80 to 90 percent., It is due to fuel consumption and emissions of air pollution and greenhouse gases that are said to drive global warming.

So, the correct option is '80%'.

Which of the following pollutants are released by burning fossil fuels and reduces visibility, especially in cold weather, when water also condenses out of the air?

  1. Oxides of Sulphur

  2. Oxides of Nitrogen

  3. Unburnt carbon particles

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

On burning, fossil fuel with minimum oxygen supply is given unburn carbon particle which doesn't settle down and get mix with water vapour. In winter it gets worse, visibility of air get dropdown and very hard to breath because of a minute particle present in the air. Sulphur and Nitrogen are also harmful but they are not involved in visibility problem.

so the correct option is 'Unburnt carbon particles'.
