Answer 2

$\huge\bf{\underline{\green{Answer:-}}}$

Calorific value can be defined as the amount of heat produced by the combustion of 1 gram of q fuel completely. This is known as calorific value of q fuel. As we know that, if the calorific value of q fuel is more than the other fuel that means the amount of heat produced by the combustion of 1 gram of fuel completely, more than the other fuel, it is the best fuel.

Yes, we can say that coal is a better fuel than wood.

$\huge\bf{\underline{\green{Reasons:-}}}$

→ Coal has it's high calorific value than that of the wood. So, people think that coal is better than that of the wood. And so people use coal and burn coal as a fuel which is used in cooking purpose.

→ Coal produce less amount of carbon dioxide gas and carbon monoxide gas as comparison to the wood because wood produces much amount of carbon dioxide gas and carbon monoxide gas.
