Mains gas is most likely to be piped natural gas. The most serious risk to human health is via a leak‚ however small‚ in the piping system that transports the gas inside the building. Natural gas is a mixture of hydrocarbons‚ including methane. It is colourless and odourless‚ which makes a leak difficult to notice. Exposure to high levels of natural gas quickly causes unconsciousness and even death. Exposure to low levels can cause dizziness‚ nausea or heart palpitations. It has this affect because

Sarin Gas Sarin Gas is one the most deadly and toxic gases that has no color and no scent. The formula for this chemical is C4H10FO2P or a more complicated formula or CH3P(=O)(F)(OCH(CH3)2) . This destructive weapon was innovated as a herbicide during the 193040s which is labeled as a nerve agent. Sarin is capable of causing the fatality of someone or the suffocating of a person by just inhaling a low concentration of Sarin gas. Sarin is considered a chiral molecule since it contains four chemical

Hazardous Chemical Mustard Gas Imagine sitting in a trench during World War 1 with your fellow soldiers and someone shouts‚ “Incoming!” you duck deeper into the trench and fumble for your helmet‚ not realizing that it could be your last seconds on this earth. Instead you smell a pungent mustard aroma‚ struggling to breath‚ it subsides after a couple of minutes. Without knowing it you have been exposed to a new chemical used by the Germans‚ code named LOST‚ which referred to the last names of the

are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much

Plant derives their power from gas burning. LNG Power Plant can use gas engine or gas turbine as their power generating unit. Generally gas turbine design for simple & combine cycle with rugged components for base load utility service but also can start & stop easily for peaking application. In the other hand‚ gas engine design for wide variety of application‚ and provide fast and flexible capacity with multiple unit. This comparation of gas engine and gas turbine advantages and disadvantages

Shale gas: Pro and Cons for UK Abstract Introduction Shale gas is natural gas that is found in shale formations. It is becoming increasingly important as major nations are beginning to become involved in this revolution. The gas is rich in petroleum and natural gas. Unlike conventional natural gas‚ which is in permeable rocks like sandstone‚ gas cannot flow through the shale. Therefore‚ just drilling a well isn’t enough to extract this gas. As a result of this‚ fracking or hydraulic fracturing is

Objective The purpose of the Jominy test in this experiment is to determine the hardenability of three types of steels‚ namely EN 8‚ EN 16 and EN 24. Introduction This report will try to illustrate how the hardenability of these types of steels vary and why. This will be done by using the Jominy end quench test on each of the test pieces and then testing the hardness of the particular steel from the quenched end‚ to the end of the test piece. Taking these different points will enable me to find

embargo was skyrocketing energy prices as a result of limited supply and heavy demand. Rationing went into effect‚ with supplies of petroleum products being carefully doled out with ration cards and flag systems‚ in which people could take turns buying gas and other fuels on the basis of license plate numbers. At the same time‚ the stock market contracted radically‚ an event that foreshadowed future stock market instabilities linked to the price of oil. The 1970s was also an era in which environmentalism
