gas field operations

This is a gaseous mixture of lower hydrocarbons, which covers crude oil in an oil field. Natural gas mainly consists of methane, which burns without smoke, and leaves no ash. It is an ideal fuel and can be used for heating, generating electricity, and also as a raw material for..

Helium - Neon Gas Laser - The figure shows the elements of a type of laser that is often found in student laboratories. The glass discharge tube is filled with a 80%-20% mixture of the inert gases helium and neon. Helium is the "pumping" medium and neon is the "lasing" medium. The above f..

(i) Nitrogen is used in high temperature thermometers where mercury cannot be used. This is because mercury boils at 356.7 o C and hence cannot be used in such thermometers. A volume of nitrogen is enclosed in a vessel and introduced into the region of high temperature. Depending upon the temperatu..

Nitrogen gas is mainly used for the manufacture of compounds such as, ammonia, nitric acid, calcium cyanamide etc. Nitrogen gas is used for providing inert atmosphere in many metallurgical operations. Liquid nitrogen is used for producing low temperatures requi..

Chromosomal Basis of Inheritance - Heredity depends upon the protoplasmic continuity between the parent and the offspring. It is the gametes that establish the continuity between parent and offspring and hence, the mechanism of inheritance operates across this exceedingly slender protopla..

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 separation. ..

The particles are separated by much greater distances, almost 10 to 100 times the size of the particles. The operating forces of attraction are virtually non-existent in gases, resulting in loosely packed particles, which are free to move in any direction. Thus gases possess neither defi..

Travel in straight linesThey cast a shadow of the objects placed in their way. Produce mechanical effectA paddle wheel placed in their path starts rotating. Rays are positively chargedWhen an electric field is applied in the path of anode rays, they are deflected towards the negat..

Question: What are anode rays? State three properties of anode rays. Answer: Anode rays are stream of positively charged particles shot out from the anode of a discharge tube when a current is passed through a gas. Anode rays travel in straight lines. They cast shadows of t..
