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.
What else can I help you with?
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?
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.
1. An unknown clear liquid is given to you in a beaker. You transfer the liquid from the beaker to a clean empty test-tube and begin to heat it. After a while you see vapors (which on further analysis?
indicate that the liquid is likely water or a water-based solution due to the formation of vapors upon heating. If the vapors condense back into liquid, it suggests that the substance has a relatively low boiling point. Further analysis, such as observing the boiling point and conducting additional tests, can help identify the composition of the liquid more precisely. If the vapors produce a specific odor or react with indicators, it could provide further clues about the liquid's identity.
Is gasoline heavier than mercury?
No. Mercury is a liquid metal and is more dense.
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.
Is ether or gasoline more flammable?
Ether is generally more flammable than gasoline. It has a lower flash point, meaning it can ignite at a lower temperature, and its vapors can easily ignite in air. Additionally, ether's high volatility contributes to its ability to form flammable mixtures more readily than gasoline. Therefore, while both are flammable, ether poses a greater fire hazard.
Is hydrogen more flammable than gasoline?
Yes, hydrogen is more flammable than gasoline.
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?
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 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?
There are far more than five. Ethanol, methanol, 2-propanol, pentane, and hexane are five extremely common examples.
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.
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.
What is flammable organic or inorganic?
Usually organic compounda are more flammable than inorganic
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.
