Question

Which of the following is not a green house gas?
A.Methane
B.Carbon dioxide
C.Nitrous oxide
D.Ammonia

Answer 1

Hint: The gas which is not a greenhouse gas has a very pungent smell. It is a binary compound made up of the nitrogen. It is colourless and soluble in water. It causes irritation in the eyes when it comes in direct contact.

Complete step by step solution:
GreenHouse Effect is the warming of earth due to remission of sun's energy absorbed by the earth. The remission of earth's energy is absorbed by carbon dioxide gas that is \[{\text{C}}{{\text{O}}_2}\] molecules and \[{{\text{H}}_2}{\text{O}}\] vapour or water vapour present near the earth's surface and then its radiation back to the earth, is called as greenhouse effect. So the temperature of earth is increased this is what is called as global warming.
Relative contribution of various greenhouse gases to total global warming: Carbon dioxide 60 percent, Methane 20 percent, chlorofluorocarbons (CFCs) 14 percent, Nitrous oxide 6 percent. Greenhouse gases absorb long wave (infrared) radiation from the earth and emit it again towards the earth. The cycle continues till the earth's surface has no long wave radiation to emit. We can control global warming by cutting down use of fossil fuels, improving efficiency of energy usage, reducing deforestation, planting trees and slowing down the growth of human population.
All the gases are greenhouse gases except ammonia.

Thus, the correct option is D.

Note: Green house chambers serve as a site for plants like tomatoes to grow inside for early flowering and fruiting especially during winter because the glass panel lets the light in but does not allow heat to escape.
