(Molar mass of CH 4 =16) The fuels are graded, and priced on the basis of their calorific values. Amongst the fuels, hydrogen has the highest calorific value. But, hydrogen is not used as the domestic/industrial fuel because of the following reasons: Hydrogen has a very low boiling point...

Fuels such as coal, petroleum and natural gas, which undergo combustion (burnt in air either alone or after mixing with another substance) and release energy are needed for the working of machines. The energy released keeps the machines working. More is the energy released, better is the fuel. Hum..

Introduction - We observe various chemical processes in our daily life. It is a common observation that the rates of these chemical reactions vary and depend on certain factors. The knowledge of the rate of a reaction is of importance in industries to ensure optimum productivity. An ..

1. For drinking and for life processes. On an average, a man consumes about 60,000 to 80,000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up. Aqueous solutions fill the cells..
