28 liquid nitrogen

= 10 (ii) R.D of liquid = 0.9 2. A solid weighs 32 gf in air and 28.8 gf in water. Find how much will it weigh in a liquid of R.D 0.9. Suggested answer : R.D of liquid 0.9 0.9 x 3.2 = x x = 2.88 gf Weight of solid in liquidh..

Water is the most common liquid. Density of water at 4 o C is 1 g cm - 3 (1000 kg m - 3 ). Example : 28 kg of fuel completely fills a 40 liter petrol tank of a vehicle. What is the density of the fuel? (1 liter = 10 - 3 m 3 ) Suggested Answer : Mass of fuel = h..

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 different steps involved in nitrogen fixation are as follows: 1) Atmospheric nitrogen is reduced by the addition of hydrogen atoms. 2) As a result the there bonds between the two nitrogen atoms are broken down resulting in the formation of ammonia. 3) ..

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 ..

Fluids Pressure Upthrust and Flotation..

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..

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 = (..
