1) We do not use coal gas as a fuel because it has a relatively low calorific value, moreover, it produces a large amount of smoke causing pollution.
2) Petroleum does floats on water 'cause petroleum has lower density than that of water.
3) ● Using less gas stoves.
● Increase in the use of induction stoves.
● Using solar cookers for cooking.
