What is a fuel? Why do we use different fuels for cooking, vehicles, and industries? In this video, we explore the meaning of fuel, what makes a fuel “good,” and why no fuel is truly ideal. Learn how fuels are classified into solid, liquid, and gaseous types, and understand the key features of an ideal fuel like cost-effectiveness, safety, and energy output.

In this video, we explore the concept of fuel efficiency and the importance of calorific value — the amount of heat produced by burning 1 kg of fuel. You’ll learn how different fuels like wood, coal, LPG, and CNG compare in terms of energy output and why cleaner, high-calorific fuels are preferred.
