Detailed explanation-1: -A good fuel should have a high calorific value so that it can give us a sufficient amount of heat per unit mass. It should also have a moderate ignition temperature so that it burns easily, this means that it should neither be too low nor too high.
Detailed explanation-2: -A fuel is considered good or valuable if it has a low ignition temperature and it produces a large quantity of heat and has high calorific value. Ideal fuels should be easy to store, leave behind no ash after being burnt and burn easily.
Detailed explanation-3: -Ideal fuel should have a proper ignition temperature, so that it can be burned easily. The ignition temperature of an ideal fuel should neither be too low nor too high. If the ignition temperature of the fuel is very low, then the fuel will catch fire too easily and hence it will be very unsafe to use it.
Detailed explanation-4: -(a) high calorific value and low ignition temperature.
Detailed explanation-5: -(b) What are the characteristics of an ideal fuel (or good fuel)? (c) The calorific value and ignition temperature of fuel A are 55 kJ/g and 80°C, respectively.
