Natural Gas and Coal Concepts

The video tutorial explores the topic of coal and petroleum, focusing on their classification as natural resources. It explains the formation of fossil fuels through carbonization and details the uses and by-products of coal, such as coke, coal tar, and coal gas. The tutorial also covers the formation and refining of petroleum, highlighting the process of fractional distillation and the significance of oil wells. Additionally, it discusses the uses of natural gas, its environmental impact, and strategies for reducing pollution from fossil fuels.
