1.	Carbon dioxide (CO2) is largely contributed by __________(a) vehicles(b) power plants(c) humans(d) plantsThis question was addressed to me during an interview for a job.This key question is from Environmental Aspects of Power Generation topic in chapter Steam Generators & Accessories of Energy Engineering
Answer» The correct answer is (b) power plants For explanation: Carbon dioxide is largely contributed by power plants. CO2 added to NATURE by natural causes viz., decay of organic matter contributes more than that by artificial causes. Also CO2 contaminants in ATMOSPHERE are not considered as pollutants as it is ESSENTIAL for plants.
