What is meant by calorific value?

Calorific value is the amount of energy released or produced when 1 kg of fuel burns or any other substance is burnt in the presence of oxygen and the products of combustion are cooled to STP. Its SI unit is kJ/kg.

Why petrol catches fire easily than kerosene?

Answer: Petrol catches fire more easily because its ignition temperature is lower than kerosene. Petrol catches fire with very small amount of heat. Q. Answer: The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances.

What is a good fuel?

A fuel is considered good or desirable when it has a low ignition temperature and generates a significant amount of heat. It reflects it high in its calorific value. Ideal fuels should be easy to store, leaving behind ash after they are burned and quickly combust.

Which fuel has highest calorific value?

Natural gas is mainly Methane and has the lowest carbon-to-hydrogen ratio of the fossil fuels and the highest calorific value of about 55 MJ/kg, although this value will be lower if the methane content in the gas is lower.

Which gas is released by burning coal?

carbon dioxide

Why is LPG a good fuel?

LPG is an energy-rich fuel source with a higher calorific value per unit than other commonly used fuels, including coal, natural gas, diesel, petrol, fuel oils and biomass-derived alcohols. This means that an LPG flame burns hotter, an advantage that can translate into higher efficiency.

How does carbon dioxide control fire?

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.
