The earth is the Unique planet since life is possible only on earth. There are some reasons for the survival of life on the earth. Proper temperature, the presence of water, the blanket of the Ozone layer and presence of Oxygen in the atmosphere. Now the temperature is rapidly increa...
If the pressure exerted by ozone, O_3, in the stratosphere is 3.0 \times 10^{-3} atm and the temperature is 250 K, how many ozone molecules are in a liter? If the pressure exerted by ozone, O3, in the stratosphere is 3.0 x 10-3 atm and the te...
hydrolysis to form NH 3 or NH 4 + ) is useful to living organisms. Nitrogen on present-day Mars has been analysed only in the atmosphere. The inventory is a small fraction of the amount of nitrogen presumed to have been received by the planet during its accretion. Where is the missing ...

The simplest application of SAI is spraying H2SO4 in the upper atmosphere. This is the equivalent of a volcanic eruption, and causes the amount of sunlight being reflected back into space to increase. However, H2SO4 is sulfuric acid, it’s nasty stuff. And it takes a long time to ...
In the atmosphere, volatile compounds and particles generated by volatilization and recondensation of semivolatile organic compounds are subject to reactions with atmospheric radicals (OH, O3, and NOx) in the presence of ultraviolet light. These reactions create the potential for chemicals from tire ...
A BPSG layer serving as a silicon oxide layer is formed on a semiconductor substrate 1. Formed on the surface of the BPSG layer is a hydrophobic molecular layer comprising hydrophobic groups such as m
