Why does the petrol fraction have a lower viscosity than the fuel oil fraction?
Petrol has a lower viscosity than fuel oil because petrol is a more refined product consisting of lighter hydrocarbons, while fuel oil contains heavier hydrocarbons and impurities. The lighter hydrocarbons in petrol flow more easily due to weaker intermolecular forces, resulting in lower viscosity compared to the heavier hydrocarbons in fuel oil.
Is kerosene more viscous than petrol?
Yes, kerosene is generally more viscous than petrol (gasoline). Viscosity refers to a fluid's resistance to flow, and kerosene, being a heavier hydrocarbon, has a higher viscosity compared to the lighter hydrocarbons found in petrol. This difference in viscosity affects their handling, combustion properties, and applications in engines and fuel systems.
How do you change the viscosity of honey?
You can change the viscosity of honey by adding water. While you will no longer have pure honey, the water will change its viscosity. The viscosity of pure honey is approximately 10,000 cP at 20°C and at 1 atmosphere. However, this will vary with the type of honey you have.
How could you change the viscosity of the substances?
You can change the viscosity of a substance by adjusting its temperature- generally, increasing temperature decreases viscosity and vice versa. You can also alter the composition of the substance by adding viscosity modifiers or solvents to increase or decrease viscosity accordingly. Mixing different substances together can also affect the overall viscosity of the mixture.
How does temperature affect viscosity of motor oil?
Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).
What is most viscous petrol diesel gas kerosene bitumen?
Bitumen is the most viscous among petrol, diesel, gas, and kerosene. Viscosity refers to a fluid's resistance to flow, and bitumen is a heavy, tar-like substance with a high viscosity. In contrast, petrol and gas are lighter and flow more easily, while diesel has a moderate viscosity, higher than petrol but lower than bitumen. Kerosene sits between petrol and diesel in terms of viscosity.
What are 2 low viscosity liquids?
petrol and water

What sensor is used in order to determine the viscosity of petrol in vehicles?
the o2 sensors
Viscosity of gasoline?
The viscosity of diesel fuel is directly dependent upon the temperature at which it's kept. At 100 degrees, the viscosity may be as much as 140 SSU. The higher the temperature, the lower SSU, so at 130 degrees the viscosity may only be 70 SSU.
How would you define viscosity - index?
Viscosity index is a measure of how an oil's viscosity changes with temperature. Higher viscosity index oils are more resistant to changes in viscosity with temperature, making them perform more consistently across a range of temperatures.
Is viscosity a chemical or a physical change?
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.
What is thicker fuel oil or petrol?
Fuel oil is thicker than petrol because it has a higher viscosity and density. Fuel oil is used in heating systems and diesel engines, while petrol is used as a fuel for gasoline engines in cars.
Which is more viscous diesel or petrol?
Diesel has a much higher viscosity than petrol (gasoline). It is less refined and contains more oil to lubricate and cool the combustion chamber in a diesel engine.
How do you change the viscosity of honey?
You can change the viscosity of honey by adding water. While you will no longer have pure honey, the water will change its viscosity. The viscosity of pure honey is approximately 10,000 cP at 20°C and at 1 atmosphere. However, this will vary with the type of honey you have.
What is easy to evaporate motor oil or water or petrol?
Petrol or gasoline will evaporate fastest. Water is next and motor oil would be the slowest. Factors include temperature, viscosity and surface tension of the liquid.
