Petrol is obtained from crude oil by fractional distillation and subsequent mixing of some of the fractions to obtain the desired properties. There are seasonal differences in petrol to facilitate vehicle operation under different climactic conditions. Some of the fractions for the petrol may be obtained by "cracking" higher molecular weight fractions to lower molecular weights. Some impurities, like sulfur, and some unsaturation of the fraction may be removed by treatment with hydrogen which replaces the impurity on the hydrocarbon molecule or adds hydrogen to the molecule to make it more stable. Some of the fractions may be treated to rearrange some of the molecules to make a more desireable product. It is a complex process that is highly dependant on the crude source, desired products, time of year, and the configuration of the refinery. From the same crude may come: fractions for making plastics, rubber, heating oil, diesel and gasoline fuels, lpg fuel, lubricants, solvents, petroleum coke, elemental sulfur, asphalt, bunker fuel oil, etc.
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
pH has NO VALUE in petrol, becuase it is immischible with water.
Petrol, also known as gasoline, is primarily made from crude oil through a refining process. Crude oil is a fossil fuel found underground and consists of hydrocarbons. The refining process separates these hydrocarbons into different products, with petrol being one of them.
Petrol contains volatile compounds that have low boiling points, so they easily evaporate when exposed to air. As the air around the petrol is warmer than the petrol itself, the vaporization process is accelerated, causing the petrol to evaporate.
Petrol and paraffin can be separated using fractional distillation, a process that takes advantage of their different boiling points. Petrol has a lower boiling point than paraffin, so when heated, petrol vaporizes first and can be collected separately from paraffin.
in petrol we have 2 types.they are 1.leaded petrol 2.unleaded petrol in leaded petrol we have lead compounds so we call it as leaded petrol. in unleaded petrol we do not have lead compounds. the use or advantage of unleaded petrol is it does not emit harmful gases in to the environment. but leaded petrol emits harmful gases. cracking process takes place in unleaded petrol. cracking means it is a process of converting harmful gases into harmless gases. but this cracking process cannot be done in leaded petrol bcoz lead compounds decomposes the catylsts used in cracking process
Yes, the viscosity of petrol can change with temperature. As temperature increases, the viscosity of petrol decreases, making it flow more easily. Conversely, at lower temperatures, the viscosity of petrol increases, making it flow more slowly.
Yes, petrol evaporates at normal temperatures. When exposed to the air, petrol will slowly evaporate and turn into vapor. This process is why you can smell petrol when you are near it.
Yes, petrol and water can be separated using a process called gravity separation. Petrol, being less dense than water, will float on top of the water, allowing them to be easily separated. Alternatively, a specialized separation technique like distillation can also be used to separate petrol and water more effectively.
Yes. It is refined from crude oil in a process known as cracking.

petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite. petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite.

Mostly in the combustion process.
