liquefaction of gases of noble gases

Noble Gases - The amount of all the noble gases put together (Helium, Neon, Argon, Krypton, Xenon and radon) is extremely low in air. These form only 0.94% of the volume of air and as such can be treated as negligible. These gases were found chemica..

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..

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 ..

Noble gases are also known as inert gases and do not take part in chemical reactions. They have their outermost shell complete and thus remain stable. They do not generally combine with other substances, nor are they affected by oxidization agents or by reducing agent..

Powdered dry ice and ether or acetone, when mixed together, can reduce the temperatures to about -220 o F. At this temperature it is used in liquefaction or solidification of gases..

Uses of Noble Gases - Argon is used mainly to provide an inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. It is also used in the laboratory for handling substances that are air-sensitive. Helium is a n..

Argon is used mainly to provide an inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. It is also used in the laboratory for handling substances that are air-sensitive. Helium is a non-flammable and light gas. Hence, it is u..
