Petrol, or octane, has no surface tension because it is a non-polar molecule. Water is very polar, meaning the water molecule has a positive end and a negative end. This causes hydrogen bonding, an inter-molecular attraction, between water molecules. This in turn causes surface tension, which binds water into droplets, and explains many of water's properties. So, petrol evaporates more quickly than water and pours easier.

Water molecules have polar characteristics. They have strong intermolecular bonds, namely, hydrogen bonds. But the only intermolecular force present between petrol molecules is London forces which is relatively very weak than hydrogen bonding.

Volatile is defined as likely to change in a very sudden or extreme way. Gasoline is more volatile than water because of its chemical make up.

Oxygen is required for gasoline to burn. There is far more oxygen in gasoline vapor than in liquid gasoline. This is why the flame is on top of a puddle of gas. Just the vapor is burning.

Why does gasoline ignite?

Gasoline ignites because gasoline is flammable. (simple answer) A more detailed answer would be. Gasoline produces flammable vapors at a much lower temperature than almost any other 'common' chemical. It is the vapors that ignite rather than the chemical itself. Also Gasoline vapors are heavier than air. Any 'Flammable' chemical will ignite in the presence of an open flame or spark if there are sufficient fumes.


What is more flammable than gasoline?

The flammablilty of liquids is measured by flash point this is the minimum temperature in which a spark will ignite it. Gasoline which is a mixture has a flash point of around 0 degrees C. One of the most flammable liquids, Diethyl ether has a flash point of -45 degrees so is much more flammable than gasoline.


Is gasoline more explosive than gas?

In general gasoline is not more explosive then gas although it depends on the conditions and the gas. Probably you are referring to natural gas, the gas piped into homes which is predominantly methane. In general flammable gasses are more explosive than flammable liquids because they are mixed up with atmospheric oxygen. This is why modern cars have fuel injection which sprays the petrol to make it more easily combustible. In fact liquid petrol is not explosive at all but because it is volatile a layer of vapour forms above the surface of the liquid which is explosive. The mix of fuel and oxygen is the critical factor in whether something is explosive. Some gases, such as the noble gases are not flammable at all.


Why don't air balloons use hydrogen gas?

Because hydrogen is EXTREMELY flammable and can burn from a wide range of air concentrations. It is more flammable than gasoline.


Which type of product is most likely to explode if stored next to a heat source?

Anything flammable or more likely anything that is in a compressed cylinder in liquid or gas form. E.G. Nail polish, air freshener, gasoline.


What is more flammable hexane or potassium sulfate?

Hexane is a highly flammable liquid, C6 H14. Potassium sulfate is an inorganic salt. You'll never get it to burn.


Do Liquid flammables ignite more easily than do liquid combustibles.?

In common usage flammable liquids are the same as combustible liquids in terms of their ability to catch fire. However, in the technical usage of hazardous materials transportation and of fire prevention, a combustible liquid has a higher flash point than a flammable liquid and is therefore less easily ignited. So, yes, flammable liquids ignite more easily than do combustible liquids.


Is gasoline heavier than mercury?

No. Mercury is a liquid metal and is more dense.


Which is more flammable kerosene gasoline lighter fluid or paint thinner?

I know for 101% sure that gasoline is the most flammable charcoal lighter fluid contains Kero and Naphtha that would be second,kero is 3rd, and paint thinner lets say Gum Turpentine an old school paint thinner is almost as flammable as kero so its 4th. But i know you can use Gum turpentine to fuel kerosene lamps.

Why is fueling a car while it is running not recommended?

Gasoline fumes are flammable. A running car generates heat and electricity and is more likely to be an ignition source.
