Which of the following fuels is a charasteristic of a good fuel?
-
high calorific value
-
low ignition temperature
-
high oxygen content
-
none of these
A
Correct answer
Explanation
A good fuel should have high calorific value to provide maximum energy. Low ignition temperature would be dangerous (fuel could ignite too easily). High oxygen content is not desirable as it reduces the energy density. Therefore, high calorific value is the correct characteristic.
