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.

Gasoline vapors are more flammable than liquid gasoline because they have a wider flammable range, meaning they can ignite at lower concentrations in the air. Vapors are also more easily mixed with air to form an explosive mixture. Additionally, vapors have a higher surface area to volume ratio, allowing them to ignite more quickly when exposed to a spark or flame.

∙ 14y agobecause it contains oil and oil doesnt mix with water. =)

∙ 13y agoOxygen 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.

Are the products or reactants more dangorious in burning gasoline?
The reactants (gasoline vapors) are more dangerous in a gasoline fire, as they are highly flammable and can ignite easily. The products of combustion (carbon dioxide, water vapor, carbon monoxide) are a byproduct of the burning process and are less hazardous in terms of fire risk.
Is gasoline volatile?
Yes, gasoline is volatile because it can easily evaporate into the air at normal temperatures. This volatility is what makes gasoline highly flammable and able to ignite easily.
Why is an empty gasoline drum more dangerous than a full one?
An empty gasoline drum is more dangerous than a full one because it is more prone to igniting vapors due to increased air space inside the drum. This can create an explosive atmosphere if there is any ignition source nearby. With a full drum, there is less air space for vapors to accumulate, reducing the risk of ignition.
Is gasoline heavier than mercury?
No. Mercury is a liquid metal and is more dense.
Are combustible liquids more of a fire hazard than flammable liquids?
It is harder to start a combustible liquid buring than to start a flammable liquid burning. In most cases, however, neither type of liquid is "unstable." Both are simply liquids that can burn if ignited. Being "unstable" means that it might detonate or explode.
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.
Are the products or reactants more dangorious in burning gasoline?
The reactants (gasoline vapors) are more dangerous in a gasoline fire, as they are highly flammable and can ignite easily. The products of combustion (carbon dioxide, water vapor, carbon monoxide) are a byproduct of the burning process and are less hazardous in terms of fire risk.
Is gasoline more explosive than gas?
Gasoline is more explosive than natural gas. Gasoline is a liquid fuel that vaporizes easily and can create a highly flammable mixture with air, while natural gas is primarily composed of methane which is less explosive than gasoline.
Why is Kerosine safer than Gasoline?
Kerosene is considered safer than gasoline because it has a higher flash point, which means it is less likely to ignite at normal temperatures. Additionally, kerosene produces less flammable vapors compared to gasoline, reducing the risk of accidental fires or explosions.
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.
What 5 substances can be classified as liquid and flammable?
Gasoline Ethanol Acetone Diesel Methanol
Is gasoline volatile?
Yes, gasoline is volatile because it can easily evaporate into the air at normal temperatures. This volatility is what makes gasoline highly flammable and able to ignite easily.
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 flammable organic or inorganic?
Flammable organic materials are those derived from plants or animals, such as wood, paper, or gasoline. Inorganic materials that are flammable include substances like magnesium or phosphorus.
What is more flammable hexane or potassium sulfate?
Hexane is more flammable than potassium sulfate. Hexane is a highly flammable liquid that can easily ignite when exposed to a flame or spark, while potassium sulfate is a solid compound that is not flammable under typical conditions.
Does liquid gasoline expand?
Yes, liquid gasoline can expand when heated. As it absorbs heat, the molecules within the gasoline move more rapidly, causing them to spread out and take up more space, leading to expansion.
Which is more flammable kerosene gasoline lighter fluid or paint thinner?
Gasoline is generally more flammable than kerosene, lighter fluid, and paint thinner. It has a lower flash point and is more volatile, making it highly flammable and dangerous if not handled properly.
