Looking for a Gas Gas is everywhere. There is something called the atmosphere. That’s a big layer of gas that surrounds the Earth. Gases are random groups of atoms. In solids‚ atoms and molecules are compact and close together. Liquids have atoms that are spread out a little more. Gases are really spread out and the atoms and molecules are full of energy. They are bouncing around constantly. Gases can fill a container of any size or shape. It doesn’t even matter how big the container is. The

Conservation of energy and transformation of energy. By Paige‚ Stacie‚ Amelia. Objectives Learning about Conservation of energy Learning about transformation of energy Conservation – Preserving a substance. Metabolism Metabolism is a process in which you break down foods into calories and these are combined with oxygen to release the energy that your body needs in order to function/live. This is a very complicated bio-chemical process. Metabolism is essential for the energy for these functions:

CHAPTER 1: NATURAL GAS IN INDIA * Importance of natural gas Natural Gas is a new age fuel. Natural Gas is the cleanest of fossil fuels. Natural Gas satisfies most of the requirements for fuel in a modern day industrial society‚ being efficient‚ non-polluting and relatively economical. Natural Gas requires a strong distribution network to not only support existing demand‚ but also fuel future demand. A big challenge lies in bridging the physical gap between demand and supply centers in an efficient

What is crude oil? Crude oil is a naturally occurring liquid found inside certain rocks trapped beneath the Earth’s crust. It is dark and sticky‚ classified as a hydrocarbon‚ or rather mixture of hydrocarbons. We separate them in order to make something useful during a process called fractional distillation. Since it is highly flammable and can be burned to make energy‚ it is used as a major fuel source on our planet. This oil is a fossil fuel‚ what means that there is a limited supply

Although Helium exists in the atmosphere of Earth in small quantities‚ it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

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
