the advantages of using gas

Natural Gas - It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its gre..

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..

has no definite volume or shape is fluid is very compressible. It takes the volume and shape of the vessel in which it is kept. For example: Hydrogen and carbon dioxide All the three states of matter are inter-convertible. For example: water When water is cooled to 0 o C, it transforms i..

. A domestic gas cylinder whose main constituent is butane, contains about 14 kg of LPG. A strong smelling substance (Ethyl mercaptan C 2 H 5 SH) is added to LPG gas cylinders to help in the detection of gas leakage. The gas used for domestic cookin..

The specific heat of a substance is the amount of heat required to increase the temperature of a unit mass of it through a unit temperature. Its units in cgs system are cal g -1 o C -1 . In mks system, it is measured in kilocal kg - 1 o C - 1 . The SI unit is J kg - 1 K - 1 . The above definition i..

>We are calling the total mass m t o t , because later on in the chapter, we use m for the mass of one molecule. Measurements of the behavior of various gases lead to several conclusions. First, the volume V is proportional to the number of moles n. If we double the number of moles, keepi..

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 figure is a simplified version of the..

A liquefied form of natural gas usually consists primarily of methane. Its properties are those of liquid methane, slightly modified by minor constituents. One property, which differentiates liquefied natural gas (LNG) from liquefied petroleum gas (LPG), which is prin..
