eat liquid nitrogen

Many liquid pollutants are evolved during the process of manufacturing pesticides, medicines and other chemicals. Liquid pollutants are also released during the process of refinement and processing. Some of them are dangerous and cause serious implications on drinking water qual..

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 ..

>(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..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (..

Velocity of Sound in Liquids and Solids - modulus of the liquid r is its density. For water, at a temperature of 20 o C, B = 2.05 x 10 9 Nm - 2 and r = 1000 kmg -3 The velocity of sound in water was determined by Daniel Colladon and Jacob Sturm in the lake of..

Suppose a horizontal area A (m 2 ) is supporting a column of liquid of height h (m) and density d (kgm - 3 ..

When a solid body is immersed in a liquid and then in water, the volume of displaced liquid is the same as the volume of displaced water which is equal to the volume of the solid. R.D of liquid Since the volume of displaced liquid = Volume of displaced w..

Record the observations as shown below: Weight of the sinker in air = W 1 gf Weight of the sinker in water = W 2 gf Weight of the sinker in liquid = W 3 gf Loss of weight of the sinker in water = (W 1 - W 2 ) gf Loss of weight of the sinker in liquid = (..

Summary - Nitrogen is the first member of group VA. Nitrogen has 5 electrons in its valence shell. It has a valency of 3 with respect to hydrogen and a valency upto 5 with respect to oxygen. It is a non-metal and its oxides are acidic in nature. Nitrogen is an importan..
