Coal is formed in nature by the 'carbonisation' of wood. Conversion of wood to coal under the influence of high temperature, high pressure, and in the absence of air is termed carbonisatio..

Here the aim is to increase crop production. High yielding crops should be developed for this purpos..

Metals have high density and are very heavy. Iridium and osmium have the highest densities where as lithium has the lowest densit..

The installation and maintenance of an OTEC power plant is very high and efficient commercial exploitation is difficul..

Although there are more than hundred elements around us we do not find these elements in their native form in nature. This is because most of these elements are highly reactiv..

. Since the atmospheric level of the gas is only 0.3 to 0.4% and maximum crop yield is reported at 1% level, these plants are ideal for cultivation as they can draw maximum carbon dioxide from the atmosphere, greatly increasing the yield. One of the areas of current focus is the better un..

This breed is a native of Kaira and Vadodara districts of Gujarat. The average yield is 1600 to 1800 litres. The fat content is about 8-12%. This breed is highly adaptabl..

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

Light does not require a material medium for its propagation. In a given medium light travels with a very high but finite velocit..
