What is gas in simple words?
1 : a fluid (such as air) that has neither independent shape nor volume but tends to expand indefinitely. 2a : a combustible gas or gaseous mixture for fuel or lighting especially : natural gas. b : a gaseous product of digestion also : discomfort from this.
What is gas with example?
The most common example of a gas is air (the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen and carbon dioxide.
What is a gas form?
A gas is a form of matter that does not have a defined shape or volume. Gases expand to fill the space they are given.
What is gas Wikipedia?
Gas is one of the four fundamental states of matter (the others being solid, liquid, 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).
What is gas made of?
Gasoline is a fuel made from crude oil and other petroleum liquids. Gasoline is mainly used as an engine fuel in vehicles. Petroleum refineries and blending facilities produce motor gasoline for sale at retail gasoline fueling stations.
Can you see gas?
There are few gases that humans can see. Actually, gases aren’t invisible: many are quite brightly coloured. Other gases in the atmosphere (particularly oxygen, carbon dioxide and water vapour) also absorb light, but at ultraviolet and infrared wavelengths that we can’t see.
Is gas a fluid?
Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
What is gas composed of?
Many fuel gases are composed of hydrocarbons (such as methane or propane), hydrogen, carbon monoxide, or mixtures thereof. Such gases are sources of potential heat energy or light energy that can be readily transmitted and distributed through pipes from the point of origin directly to the place of consumption.
How is gas mined?
Natural gas is most commonly extracted by drilling vertically from the Earth’s surface. From a single vertical drill, the well is limited to the gas reserves it encounters.
How is a gas formed?
It is formed when layers of decomposing plants and animals are subject to intense heat from the Earth and pressure from rocks. All this pressure, heat and millions of years turned the natural material into coal, petroleum and natural gas.
Do gases have color?
Actually, gases aren’t invisible: many are quite brightly coloured. For example, nitrogen dioxide is brown-y orange, chlorine has a yellowish green hue and iodine vapour is a vivid purple (see image above).
What is a gas for kids?
Gases are air-like substances that can move around freely or they might flow to fit a container. They don’t have a shape either. Similar to liquids, gases can actually flow, but gases won’t stay put as solids or liquids do. They move around all the time.
What is the definition of a real gas in chemistry?
A real gas is a gas that does not behave as an ideal gas due to interactions between gas molecules. A real gas is also known as a nonideal gas because the behavior of a real gas in only approximated by the ideal gas law . Usually, it’s fine to use the ideal gas law to make calculations for gases.
What are facts about gases?
Gases are air-like substances that can move around freely or they might flow to fit a container. They don’t have a shape either. You could put your hand through gases and you wouldn’t feel a thing. If they get out a container they spread very easily.
What is noble gas in chemistry?
The noble gases are a group of elements in the periodic table. They are located to the far right of the periodic table and make up the eighteenth column. Elements in the noble gas family have atoms with a full outer shell of electrons. They are also called the inert gases.
What is the definition of ideal gas?
Ideal Gas Definition. An ideal gas is a gas whose pressure P, volume V, and temperature T are related by the ideal gas law. PV = nRT, where n is the number of moles of the gas and R is the ideal gas constant.
