Which of the following fuels provides the greatest amount of energy per gram?

  1. (a) CH4
  2. (b) C8H18
  3. (c) coal
  4. (d) H2

Interpretation Introduction

Interpretation: It should be determined for the following fuel provides the greatest amount of energy per gram.

Concept Introduction:

A fuel having higher calorific values is considered to be a good fuel.

Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels.

So the Hydrogen as is considers be an extremely good fuel.

But however, hydrogen gas is not used as a fuel in homes and industries.

Explanation of Solution

Reason for correct option

Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels.

So the Hydrogen as is considers be an extremely good fuel.

But however, hydrogen gas is not used as a fuel in homes and industries.

Hence the correct option for the highest calorific value is H2 option d.

Reasons for incorrect options:

Write all less calorific value of fuel, the options except option (d).

(a)CH4(b)C8H18
