liquid nitrogen

The measurable/visible properties of the system must remain unchanged with time. Once, an equilibrium is reached the properties of the system do not change with time. When equilibrium is attained, there exists an expression of concentrations of the substances involved in equilibrium, which bec..

>(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..

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..

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

A 2 m long cylindrical drum of diameter 1m is lying on its side. A dip-stick is inserted which shows a 30 cm depth of liquid. What volume of liquid is contained in the cylinder? => 0.396 m 3 or 0.208 m 3 or 0.5652 m 3 or 1.317 m 3..

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 Geneva in 1827. Two observers were stat..

Industrial - The chief source of free nitrogen is atmospheric air and nitrogen is usually prepared from it. Air free from dust, water vapour and carbon dioxide is compressed in a compression chamber for liquefaction. Firstly, the pressure on the air is increased to about 200 atm..

A 2 m long cylindrical drum of diameter 1 m is lying on its side. A dip-stick is inserted which shows a 30 cm depth of liquid. What volume of liquid is contained in the cylinder? Suppose the drum is tilted and placed vertical with the circular portion of the bottom, wh..
