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.
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.
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.
Because of the fumes. Technically if you threw a match at a gallon of gasoline and could get it past the fumes the match would go out when it hit the liquid. But the match will pass through the fumes and ignite and then the gasoline will ignite and burn or explode. So an empty barrel is all fumes and therefore an explosive environment exists in the drum.
No. Mercury is a liquid metal and is more dense.
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.
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.
Yes, hydrogen is more flammable than 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.
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.
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.
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.
There are far more than five. Ethanol, methanol, 2-propanol, pentane, and hexane are five extremely common examples.
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.
Anything flammable or more likely anything that is in a compressed cylinder in liquid or gas form. E.G. Nail polish, air freshener, gasoline.
Usually organic compounda are more flammable than inorganic
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.
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.
