Question # 1
Explain the phenomenon of decreasing temperature in troposphere
- Ans 1: Although, concentration of carbon dioxide and water vapours is negligible in atmosphere, yet they play a significant role in maintaining temperature of the atmosphere. Both of these gases allow visible light to pass through but absorb infrared radiations emitted by the Earth's surface. Therefore, these gases absorb much of the outgoing radiations and warm the atmosphere. As the concentration of gases decreases gradually with the increase of altitude. correspondingly temperature also decreases at a rate of 6C per kilometer.

Question # 1
Why is ozone depleting in atmosphere?
- Ans 1: chlorofluorocarbons (CFCs ) (used as refrigerants in air conditioners and refrigerators) are major cause of depletion of ozone layer. These compounds leak in one way or other escape and diffuse to stratosphere. Ultraviolet radiations break the C-Cl bond in CFCI3 and generates chlorine free radicals

Question # 1
State the major sources of CO and CO2 emission
-
Ans 1: Sources of oxides of carbon are as follows:• Both of these gases are emitted due to volcanic eruption and decomposition of organic matter naturally.• However, the major source for the emission of these gases is combustion of fossil fuels (coal petroleum and natural gas). Fossil fuels burnt in combustion engine of any any industry or open air fires emit CO2 and CO.Forest fires and burning of wood also emit CO2 and CO. Especially, when supply of oxygen is limited_ emission of CO dominates

Question # 1
Explain why non ionic polar compounds are soluble in water ?
- Ans 1: Water molecule is composed of of hydrogen and oxygen atom. Because of two O-H bonds and two lone pairs , one H2O molecule can form hydrogen bonding with four other H2O molecules . This unique behaviour of water enables it to dissolve many polar non-ionic compounds having hydroxyl group (-OH) like alcohols , organic acids , glucose , sugar etc by forming hydrogen bonds with them
