It exists as a gas at standard temperature and pressure . Octane is a much larger molecule with a molecular weight of 114 g/mol. It exists as a liquid at standard temperature and pressure. All gasses at room temperature and atmospheric pressure are comprised of small molecular weight molecules.
Why is propane a gas and octane a liquid at room temperature?
Methane, ethane, propane, and butane all exist in the gas phase at room temperature because they have very low boiling point. ... Notice that, if a hydrocarbon has 5 or more carbon atoms, it is a liquid at room temperature because of the increase in intermolecular forces . Octane is a liquid hydrocarbon used in gasoline.
Is octane a solid?
Generally, alkane with 4 carbons or less are gas at room temperature. As the carbon number is increased, the phases change (solid – liquid – gas). In case of octane, it is liquid .
Is water a gas at room temperature?
At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state . ... Water molecules are constantly on the move. If they are moving fast enough they become a gas. A gas is a physical state of matter where the molecules are far apart and moving very quickly.
What state is octane at room temperature?
| Formula (state at room temperature) Name | C7H16 ( liquid ) heptane hept = 7 | C8H18 (liquid) octane oct = 8 | C9H20 (liquid) nonane non = 9 | C10H22 (liquid) decane dec = 10 |

Why is octane flammable?
To start, octane, a hydrocarbon with low molecular weight, is a component of gasoline. The low molecular weight of octane makes it very flammable , giving it the volatile characteristics that gasoline needs to be effective.
What is octane used for in everyday life?
Octane number is also known as octane rating. ... The higher the octane number, the more compression required for fuel ignition . Fuels with high octane numbers are used in high performance gasoline engines. Fuels with low octane number (or high cetane numbers) are used in diesel engines, where fuel is not compressed.
Is octane a liquid or gas?
Octane is a straight chain alkane composed of 8 carbon atoms. It has a role as a xenobiotic. N-octane is a colorless liquid with an odor of gasoline.
Is propane a gas or liquid at room temperature?
The obvious answer is because propane is a gas at room temperature , while 2-propanol is a liquid at room temperature.
Can you get natural gas in a bottle?
Natural gas can be stored in natural gas bottles as either CNG – Compressed Natural Gas – or as LNG – Liquefied Natural Gas . ... A natural gas bottle (methane bottle) is different from an LPG cylinder including much higher pressure and a lower energy content. LNG is stored in a special cryogenic tank.
Is octane a girl?

Where is octane found?
Where does octane come from? It is one of thousands of different molecules found in crude oil , including alkanes, alkenes and many others. Another name for crude oil is petroleum, which is not the same as petrol.
Why isn't H2O a gas?
Water molecules are strongly attracted to each other , so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).
Why is co2 a gas at room temperature?
Oxygen is more electronegative than carbon. Therefore, the oxygens pull the electrons towards themselves with the same force on either side of the carbon atom. ... These are very weak intermolecular forces that are overcome at room temperature. Thus, carbon dioxide molecules are able to move freely as a gas .
Why is water a liquid at room temperature whereas methane is a gas?
Question: Why is water (H2O H 2 O ) a liquid at room temperature while methane (CH4 C H 4 ) is a gas? (a) Water forms hydrogen bonds and methane only form dispersion forces . (b) Water forms dispersion forces and methane forms hydrogen bonds.
