Which of the Following Solid Fuel has Higher Calorific Value?

Answer: C

Anthracite has a higher calorific value.

Solution:

Solid materials that may be burned as fuel to release energy through combustion, which produces heat and light, are known as solid fuels. The total energy generated as heat during combustion is referred to as a fuel’s calorific value.

Solid fuel	Calorific value (kJ/kg)
Wood	17000-22000
Cow dung cake	6000–8000
Coal	25000-33000
Rice husk	3607

From the above data, it is clear that the answer to the question “Which of the following solid fuel has higher calorific value?” is “coal”.
