Question

A good fuel should possess
(a) high ignition temperature
(b) moderate ignition temperature
(c) high calorific value
(d) both high calorific value and moderate ignition temperature

Answer 1

A good fuel should possess

(a) high ignition temperature

(b) moderate ignition temperature

(c) high calorific value

• (d) both high calorific value and moderate ignition temperature

Answer 2

(c) A high calorific value is the perfect answer.

Explanation:

• A proper fuel has to have an excessive calorific value in order that it may provide us enough quantity of warmth consistent with unit mass.
• It has to actually have a mild ignition temperature in order that it burns easily, because of this it has to neither be too low nor too excessive.
• The calorific value is described as warmth produced via way of means of the whole combustion of a selected amount of fuel. It is commonly expressed in joules consistent with kilogram.
• The best fuel is one that is having excessive calorific value.

A correct fuel has to fulfill the subsequent requirements:

• It has to have an excessive calorific value i.e.,
• it has to evolve a big quantity of warmth while it's miles burnt.
• Its moisture content material has to be low in order that its heating value is excessive.
• The best fuel has to have a mild ignition temperature.
