Question

What are the gases released by the combustion of coal?

• A. $C{H}_4$ and $C{O}_2$
• B. $S{O}_2$ and $C{O}_2$
• C. $N{O}_2$ and $C{O}_2$
• D. $C{H}_4$ and $N{O}_2$

Answer 1

The correct option is A

$C{H}_4$ and $C{O}_2$

The main gases that are released by burning coal are methane and $C{O}_2$ and these are responsible for all kinds of greenhouse effect. The greenhouse effect in turn causes the rise in average atmospheric temperature and that results in melting of ice caps and rise in sea level.
