AIR CHEMISTRY

1. What is Atmosphere?

   • The envelope of gases surrounding the earth or another planet.

2. How can you distinguish the different layers of the atmosphere?

   • The five main layers are: Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles) Troposnsphere: 0 to 12 km (0 to 7 miles) .

3. Why do layers of the atmosphere differ in terms of pressure and temperature?

   • There is a general decrease in temperature as elevation rises, contributing to the reduction of air pressure.

4. How do you define CLEAN AIR?

   • The absence of Air pollutants.

5. What do you think will happen if there are other gases mix with the gases in the atmosphere?

   • If other gases mix with gases in the atmosphere then It will either take over each other to be dominant or they will mix and form a new gas

6. How do you define air pollution?

   • Harmful air pollutants in the air

7. How will you be able to distinguish polluted to unpolluted air?

   • If the air is polluted then you should be able to smell the pollutants in the air. If the air is unpolluted then you should be able to smell the air without any harmful pollutants and breath properly.

8. What are the sources of air pollutant?

   • mobile sources – such as cars, buses, planes, trucks, and trains.
   • stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
   • area sources – such as agricultural areas, cities, and wood burning fireplaces.

9. What do you think are the reasons why we are releasing gases such as air pollutants to the atmosphere?

   • I think the reason why we are polluting our air is because we need resources for our daily materials and to make our lives easier.
