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.

Answer 1

Question

Chapter 20.4, Problem 1RC

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.
