important facts of liquid nitrogen

Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of respi..

Scientists connected with improvement of crop varieties are called Plant Breeders. Triticale has been developed through hybridization between Wheat and Rye. A Gene Bank is an institution where valuable plant material likely to be lost in cultivation is preserved in a viable condition, as se..

Liquid hydrogen is used as an important rocket fuel because of its low mass and high enthalpy of combustion. The chemical reaction involved is:..

Some Important Aspects of Doppler Effect - When a source moves towards a stationary observer the apparent frequency, according to equation When the observer moves towards a stationary source, the apparent frequency, according to equation In both the cases, the apparent frequency is greate..

The vapour pressure of a liquid depends upon the nature of the liquid. When intermolecular forces are weak, the molecules tend to escape readily and therefore, the equilibrium vapour pressure is high. Vapour pressure of liquids provides an indication of the magnitude ..

Expansion of container with liquid In the figure L 1 represents the original level at the level of the liquid first falls to L 2 , because the container gets heat first. When the liquid gets heated, it expands much more than the container and its level rises ..

If a bottle of perfume is opened in one corner of a room, it spreads in the whole room by diffusion. If you drop a little ink in a beaker of water it will spread by itself in the beaker of water and the color spreads uniformly. Diffusion is the natural process of intermingling of the molecules of..

>(vi) It is used by the chemical, petroleum, and paint industries to provide inactive atmosphere to prevent fires or explosions. (vii) It is used in the industrial preparation of ammonia, which is converted into ammonium salts, nitric acid, urea, calcium cyanamide fertilizers etc. (viii) Liqui..
