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.
