why should coal be used judiciously
Answers
Answer:
On the other hand petroleum is used for cooking, it is used as a fuel and for making paraffin or wax. Hence coal and petroleum are very advantageous. As they both are among the non renewable resources so they must be used wisely, because the survival without these two fossils will be very difficult.
to save for future needs
Coal and petroleum should be used judiciously because they are limited which wil soon get exhausted or finished and these also pollute our environment. Coal and petroleum were formed millions of years ago from the degradation of biomass. These are exhaustible non-renewable resources. Our known petroleum resources will last for about forty years and coal resources will last for another two hundred years only, so we should use them judiciously. When these fossil ffiels are burnt, carbon dioxide, oxides of nitrogen and sulphur and water are formed. If combustion takes place in insufficient air, carbon monoxide is formed in place of carbon dioxide. These are all poisonous at higher concentration. Carbon dioxide is a greenhouse gas increased concentration of it in the atmosphere leads to global warming.
