Examples of Gases
- carbon dioxide.
- water vapor.
- natural gas.
What are the 5 major greenhouse gases?
In order, the most abundant greenhouse gases in Earth's atmosphere are:
- Water vapor (H. 2O)
- Carbon dioxide (CO.
- Methane (CH.
- Nitrous oxide (N. 2O)
- Ozone (O.
- Chlorofluorocarbons (CFCs)
- Hydrofluorocarbons (incl. HCFCs and HFCs)
What are some examples of a gas?
Eleven elements-hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon-exist as a gas under standard pressure and temperature. Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state.
Gases are also what can make farts smell bad. Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell. Phew!
Of the many molecules and compounds coming out of the tailpipe, the EPA is primarily concerned with five of them:
- Hydrocarbons (HC)
- Carbon Monoxide (CO)
- Oxides of Nitrogen (NOx)
- Carbon Dioxide (CO2)
- Oxygen (O2)
Eleven elements-hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon-exist as a gas under standard pressure and temperature. Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state. One example is pure oxygen.
Oxygen is also a pure gas because it is made of one type of item; however, it is an elemental molecule. Pure gases may also be compound molecules, which are comprised of a bunch of different atoms. For example, carbon dioxide would be considered a pure gas but it is also a compound molecule.
Examples of solids are common table salt, table sugar, water ice, frozen carbon dioxide (dry ice), glass, rock, most metals, and wood. When a solid is heated, the atoms or molecules gain kinetic energy .
Other common industrial gases
- ammonia (NH3)
- carbon dioxide (CO2)
- carbon monoxide (CO)
- hydrogen chloride (HCl)
- nitrous oxide (N2O)
- nitrogen trifluoride (NF3)
- sulfur dioxide (SO2)
- sulfur hexafluoride (SF6)
The three states of matter are the three distinct physical forms that matter can take in most environments: solid, liquid, and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars.
What are some examples of gases used in everyday life?
- Carbon dioxide, in all kinds of fizzy beverages, and in fire extinguishers.
- Nitrogen, in cans of Guinness stout (to give it that distinctive head) and in fire suppression systems.
- Propane & Natural Gas used in gas burners and as an automotive fuel.
- Butane is used in cigarette lighters and gas camping stoves.
This gas is delivered to homes through pipelines or in tanks as CNG (compressed natural gas). Most of the natural gas consumed in homes is used for space heating and water heating. It is also used in stoves, ovens, clothes dryers, lighting fixtures and other appliances.
Smoke is a collection of tiny solid, liquid and gas particles. Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon (soot), tar, oils and ash. Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely).
Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
Fire is actually a chemical reaction. It's an oxidation reaction to be specific. When wood gets hot enough (the part of the wood that is burning) the large hydrocarbons break down to charred solids and a gas. The gas is what reacts with oxygen in the atmosphere to produced light, CO2 and H2O.
The electricity helps to strip the gas molecules of their electrons. Another example of plasma is a neon sign. Just like a fluorescent lights, neon signs are glass tubes filled with gas. When the light is turned on, the electricity flows through the tube.
Most gas stations offer three octane levels: regular (about 87), mid-grade (about 89) and premium (91 to 93). Some gas stations may offer up to five different octane ratings, including a super premium, which typically has a rating of 93.
Some of us think that it is small, minute droplets of perfume liquid (like steam is condensed water vapor in the form of liquid. Some of us think that since the perfume is volatile, that the particles that we are smelling are gas particles that have evaporated from the liquid perfume.
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. The following figure illustrates the microscopic differences.
A gas is a sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container, even in the presence of gravity and regardless of the amount of substance in the container.
The invisible part of clouds that you cannot see is water vapor and dry air. The majority of the cloud is just plain air in which the invisible water vapor is mixed with and the very tiny water drops and ice particles are suspended in. A cloud is a mixture of gas, liquid and solids.
First a nit-picking point - oxygen (O2) can be a solid, liquid, or gas depending on temperature and pressure. But I'd guess you probably already know that and are asking why oxygen is a gas at normal earth temperatures and pressures.
