What are the characteristics of gas? Gas is one of the four fundamental states of matter (the others being soli liqui and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). To describe the characteristics of a gas.
Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed. Other articles from chem. Gases have a number of special characteristics that differentiate them from other states of matter. Gases are complicated things composed a large numbers of tiny particles zipping around at high speeds. There are a number of complex forces governing the interactions between molecules in the gas , which in turn affect the qualities of the gas as a whole.
To get around these various complexities and to simplify our study, we will talk about ideal gases. An ideal gas is a simplified model of a gas that follows several strict rules and satisfies several limiting assumptions. Ideal gases can be perfectly modeled and predicted with a handful of equations. This theory describes why gases exhibit their properties.
It only applies accurately to ideal gases. Because there is no such thing as an ideal gas , the Kinetic Molecular Theorycan only approximate gas behavior. It is still very useful to chemists.
See for the exact equations of the Kinetic Molecular Theory, as well as detailed explanations. Gases can fill a container of any size or shape. What is another physical characteristic of gases ? Think about a balloon. Natural gas is consumed in the state in which it is found in nature.
From extraction at site to its arrival at homes and points of consumption, natural gas does not undergo any transformation process. Learn more about the uses and production of biogas. In its characteristics , a liquid is intermediate between a gas and a soli the other two principle states. The gas is non-poisonous. Like gases , liquids can flow and take on the shape of the container in which they are placed— characteristics not found in solids.
Like solids, liquids have a fixed volume, whereas gases do not. Then these and other properties of noble gases will be explored. Main characteristics of noble gases. On the right (highlighted in orange) is the group of noble gases.
From top to bottoHelium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn). Biogas is a renewable energy source and can be produced from organic wastes in anaerobic digesters or collected from landfills. Another characteristic property is the pressure the gas exerts on its surroundings. Many of us got our first exposure to the pressure of a gas when we rode to the neighborhood gas station to check the pressure of our bicycle tires.
LPG has two origins: approximately is recovered during the extraction of natural gas and oil from the earth, and the remaining is produced during the refining of crude oil. High methane and nitrogen compounds in. In natural gas reservoirs even the heavier hydrocarbons. LPG is thus a naturally occurring by-product. Liquids differ from solids, because their particles are not fixed and rigid and can move freely past each other.
Because liquids contain particles that can spread out and change shape depending on the container, they resemble gases. Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other.
