liquid oxygen and liquid nitrogen

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 ..

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 t..

Experiment 2: Place some crystals of potassium permanganate at the bottom of a beaker. Slowly transfer water into the beaker with the help of a pipette. After sometime a dense purple solution is formed at the bottom and you will notice that it gradually spreads with the rest of water...

The particles are loosely packed and are bound to each other with forces weaker than those of solids. This gives them definite volume but not definite shape. Thus liquids are mobile and take the shape of the container in which they are placed. Examples: Water, oil, milk e..

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..

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 = (..

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..
