principle greenhouse gas

Green house gases in the atmosphere behave much like the glass panes in a green house. Green houses are like small glass houses whose transparent glass roof and walls allow sunrays to pass through. It keeps the heat from escaping, thus allowing vegetables and flowers to grow even in cold weather. ..

Principles of Light Modulation - Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded in..

In the atmosphere, the concentration of carbon dioxide ranges from .03 to .04 %. However, it is found that 0.1% of carbon dioxide in the atmosphere increases the rate of photosynthesis significantly. This is achieved in the greenhouses which are enclosed chambers where plants are grown u..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas..

Study of photosynthesis and the factors affecting it helps us understand the most important biochemical life sustaining processes. All plants and animals are dependent on the sun for energy. This energy is made available to them by the process of photosynthesis. Man, like other animals, is depende..

. Without this natural 'greenhouse effect', temperatures would be much lower than they are now, and life as known today would not be possible. Instead, thanks to greenhouse gases, the earth's average temperature is a more hospitable 60 0 F. However, problems may arise when the a..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas. An approximate equation connecting g and the degrees of freedom is Where n is..

Pressure at a point in a liquid depends upon the depth and on the density of the liquid. The pressure at any depth in a liquid acts equally in all directions. Liquids always find their own level. Pressure applied at any point in a confined liquid is transmitted equally in all the directi..

Dissolution of a gas in a liquid can be described by the equilibrium Gas Liquid Solution When the pressure on the gas is increased, according to Le Chatelier's principle, the equilibrium shifts in a direction so as to decrease the volume of the gash..

In 1824, a French scientist N.L.Sadi Carnot, suggested an idealized engine which is called the Carnot engine, which has an intimate relation with the second law of thermodynamics. To understand the principle, let us consider an ideal gas taken in a cylinder. The bottom of the cy..
