atmospheric condition

There are some conditions associated with the process of combustion. The substance to be burnt must be combustible (the substance must catch fire easily). Wood, paper, coal, coke, hydrogen, liquified petroleum gas, natural gas, petrol, kerosene, diesel, alcohol, ether etc. are some of the..

Under standard condition of temperature and pressure i.e., when P = 1 atm T = 273.15 K V = 22.414 L mol - 1 This gives,..

The properties of temperature, pressure, humidity rainfall, sunshine cloud and wind in a given place and time is called weather . The average weather conditions of an area, which includes atmospheric conditions, seasons. etc. constitutes the climate. Weather refers to ..

Conducting experiments imperfectly, without observing all the conditions stipulated for the purpose. E.g., if the experiment is to be conducted in an air-conditioned atmosphere, if the air-conditioning system does not exist during the experiment, this error ..

Plant responses to soil conditions and atmospheric environment must be exploited to the maximum to produce a high yield per unit area of lan..

Wind Energy - Wind energy is one of the first sources of energy known to man. The sun's rays are stronger nearer the equator than in the polar region. This heats the air in equatorial region and warm lighter air rises while cooler polar air moves in to replace it. This movement of air results in wi..

Air Pollution - Humans can only live about five minutes without air. Dry air is generally a homogeneous mixture (solution) of nitrogen gas (78%), oxygen gas (21%), and traces of other gases. Some of the other gases are waste products of human activities and are known as air pollutants. Air pollutio..

Enthalpy - The change in internal energy gives the heat change accompanying a chemical reaction at constant volume. However, most of the chemical reactions carried out in laboratories, are open to normal atmospheric conditions. A chemical reaction in a laboratory may incur chang..

All the effects so far described hold true for microwave frequencies, but some are increased, and new ones are added. Atmospheric absorption and the effects of precipitation must be taken into account. So must the fact that at such short wavelengths, everything tends to happen very rapid..

For successful crop production a thorough understanding of how crops develop and grow, the various factors that affect crop growth and development and how each factor can be modified or managed are essential. Plant responses to soil conditions and atmospheric environment must be..
