gas supply services

. So, the heat supplied is assumed to increase only the temperature. However, the coefficient of expansion is very large in case of gases. Thus, if a gas is heated the heat energy is required, not only to increase the temperature of the gas but also to do mechanical wo..

Petroleum gas a by-product from two sources: natural gas processing and crude oil refining is a mixture of butane, propane and ethane. The main constituent of liquefied petroleum gas is, however, propane, propylene, butane, butylene in various mixtures. These hydrocar..

V) is, by chance, very close to level E 2 in neon (= 20.66 eV). So, during collisions between helium and neon atoms, the excitation energy of the helium can be readily transferred to the neon. In this way level E 2 can become more highly populated than level E 1 . This population inversion is maint..

It is also called exploitative forestry. The main aim of this type of forestry is to supply goods and services to meet the local demand for firewood, fodder, food, fertilizers, fibre, timber, medicines etc. It is classified into two typ..

The main aim of this type of forestry is to supply goods and services to meet the local demand for firewood, fodder, food, fertilizers, fibre, timber, medicines etc. It is classified into two types: Social Forestry and Environmental Forestry: Trees which are useful to the triba..

Community Health and Personal Health - The health of a community depends upon the personal health of the various members of the community. Community health can be defined as the personal health along with the environmental services for the importance of the health of the community. The va..

When natural gas is burnt in limited supply of air, the resulting soot is deposited on the underside of a revolving disc. This is carbon black and it is then scraped off and filled in bags. It differs from lamp black in being not so greasy. Carbon black is added to the rubber m..

We have seen that heat is just a form of energy. A system can be given energy either by supplying heat to it (by placing it in contact with a hotter object) or by doing mechanical work on it. Consider an ideal gas in a cylindrical container, fitted with a piston as shown in the ..

Let us consider one mole of an ideal gas enclosed in a cylinder fitted with an airtight and frictionless piston. Let P, V and T be the pressure, volume and absolute temperature of the gas respectively. Let heat energy Q 1 be supplied to the gas be suppli..

Highly dangerous gas with a high potentiality of causing cancer and respiratory ailments. Generally, it is evolved, when a fuel is burnt under limited supply of oxygen...
