FAQs on Fractional Distillation and Uses of Various Constituents of Petroleum Video Lecture - Science Class 8
| 1. What is fractional distillation and how is it related to petroleum? |  |
Ans. Fractional distillation is a process used to separate the different components of petroleum based on their boiling points. It is related to petroleum because petroleum is a mixture of various hydrocarbons with different boiling points, and fractional distillation helps in separating these components to obtain useful products.
| 2. What are the various constituents of petroleum that can be obtained through fractional distillation? | |
Ans. Through fractional distillation, various constituents of petroleum can be obtained. These include gasoline, kerosene, diesel, lubricating oil, and bitumen. These constituents have different boiling points, and by heating and cooling the petroleum mixture, they can be separated into individual components.
| 3. What is the use of gasoline obtained through fractional distillation of petroleum? | |
Ans. Gasoline, which is obtained as a product of fractional distillation, is primarily used as fuel for automobiles. It is a highly flammable liquid that is designed to power internal combustion engines. Gasoline is one of the most widely used fuels in the world, especially for transportation purposes.
| 4. How is kerosene used from the fractional distillation of petroleum? | |
Ans. Kerosene, another constituent obtained through fractional distillation, is commonly used as a fuel for jet engines, lamps, and heaters. It is less volatile than gasoline and has a higher boiling point, making it suitable for these applications. Kerosene is also used as a solvent and in the production of certain chemicals.
| 5. What are the uses of lubricating oil obtained through fractional distillation of petroleum? | |
Ans. Lubricating oil, which is a byproduct of fractional distillation, is used to reduce friction and wear between moving parts in machinery and engines. It provides lubrication and helps to prevent overheating and damage. Lubricating oil is used in various industries, including automotive, manufacturing, and aviation, to ensure smooth operation and longevity of equipment.
