Concept explainers
Interpretation: The reason behind the fact that UV radiation in troposphere cannot decompose the CFC should be determined.
Concept Introduction:
Greenhouse effect:
The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat. The earth’s atmosphere contains gases that radiate energy in all directions in which the part of the energy gets imparted into the earth surface.
The imparted energy makes the earth surface to have high temperature.
Conditions that greenhouse gas should fulfil is as follows,
The gas is considered as greenhouse gas if it possesses dipole moment or the vibrational motions of the gases should create some temporary dipole moment.
Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.
Dipole moment: It is the measure that describes the separation and the magnitude of charges in polar (a material is considered as polar if it has charge separation) molecule.
Aerobic respiration: It is one type of respiration in which the organisms undergoes respiration only in presence of oxygen.
To determine: The reason behind the stability of CFC.
