Abstract
The gases (they consist of three or more atoms) with higher heat capacities than those of O
2
and N
2
cause greenhouse effect. Carbon dioxide (CO
2
) is main greenhouse gas associated with global climate change. Collectively, they are projected to contribute, directly, about as much too potential global warming over the next 60 years as CO
2
. At the present time, coal is responsible for 30-40% of world CO
2
emissions from fossil fuels. There were a higher correlation between amount of carbon dioxide emission and percentage of carbon in the fuel for all equations. The squares of correlation coefficients were 0.9999, 0.9978, and 0.9995.
