1.	An increase in 1% of percentage of oxygen decreases the calorific value by ________(a) 1.7%(b) 2.7%(c) 3.7%(d) 4.7%I had been asked this question by my school teacher while I was bunking the class.My question comes from Analysis of Coal and Selection in division Fuel Technologies of Applied Chemistry
Answer» CORRECT answer is (a) 1.7% Easy EXPLANATION: The increase in 1% of oxygen RESULTS in a decrease of 1.7% of calorific value. So, always good fuel must CONTAIN LESS amount of oxygen.
