Statement 2: Hydrogen is not used as a household fuel.

• B. Both statements are right.
• C. Statement 2 is right and statement 1 is wrong.
• D. Statement 1 is correct and statement 2 is wrong.

Answer 1

The correct option is C

Statement 2 is right and statement 1 is wrong.

Calorific value is the amount of heat evolved by the combustion of 1 kg of fuel. Hydrogen has a high calorific value of 150000 kJ/kg. Higher the calorific value more efficient the fuel is. So, hydrogen is an efficient fuel. Since it has high calorific value, the chances of explosion are really high. Therefore, hydrogen is not used as a household fuel.
