liquefaction of gas

Liquefaction of Gases - There are large empty spaces (voids) separating the tiny molecules of gases from one another. Each molecule enjoys an almost independent existence. Molecules are in a state of continuous rapid motion and have negligible attractive forces between them due to wide se..

There are large empty spaces (voids) separating the tiny molecules of gases from one another. Each molecule enjoys an almost independent existence. Molecules are in a state of continuous rapid motion and have negligible attractive forces between them due to wide separation. This is particular..

Experimental observations have shown that effect of temperature is more significant in achieving liquefaction than that of pressure. This is due to the fact that for every gas there is a certain temperature above which it cannot be liquefied how so ever high the pressure may be..

Adsorption of Gases on Solids - Adsorption of gases on solids depends on the following factors: i) Nature of the gas (adsorbate) ii) Nature of the solid (adsorbent) iii) Specific area of the solid iv) Pressure of the gas v) Temperature vi) Activation of adsorbent. How these fact..

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 atmospheres. It is then re..

1. A colourless, odourless and tasteless gas. 2. Non-poisonous. 3. Its vapour density is 1. (Vapour density of air = 14.4). Thus it is much lighter than air. Passing hydrogen through soap solution can easily prove this. The bubbles formed will rise into the air. 4. Solubility of H 2 ..

: At 0K, hydrogen contains mainly para hydrogen which is more stable. At the temperature of liquefaction of air, the ratio of ortho and para hydrogen is 1 : 1. At the room temperature, the ratio of ortho to para hydrogen is 3 : 1. Even at very high temperatures, the ratio of ortho to para..
