1.	Observe the pictures and answer the question.i. What is the process shown in the given picture?ii. Explain the process.iii. What are the gaseous substances formed in the above process?iv. When the products of the process is refined, what other components are produced?
Answer» i. The process shown is formation of mineral oil and natural gas. ii. 1. Mineral oil is the liquid fuel formed by the decomposition of organic substances buried underground. 2. Millions of years ago, bodies of dead sea organisms sank to the bottom of the sea. 3. Layers of soil and sand collected on them. 4. Due to high pressure and temperature the remains of the dead organisms were transformed into mineral oil. 5. The underground mineral oil is extracted through oil wells. iii. Natural gas is also formed along with mineral oil. It contains methane, ethane, propane and butane gases. iv. When mineral oil is refined by fractional distillation products produced are petrol, diesel, kerosene, naphtha lubricating oil, tar, etc.
