(A) Combustion(B) Ignition temperature(C) Calorific value of a fuel

$\huge{\mathtt\red{Answer✓}}$

$\huge{\mathtt\blue{Combustion}}$

• the process of burning something.

"the combustion of fossil fuels"

• Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant.
• Usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

$\huge{\mathtt\pink{ignition \: temperation}}$

• The ignition temperature of a substance is the least temperature at which the substance starts combustion.
• Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.
• the lowest temperature at which a combustible substance when heated takes fire in air and continues to burn. — called also autogenous ignition temperature.

$\huge{\mathtt\pink{Calorific \: value \: of \: a \: fuel }}$

• 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.
• The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal”
• (standard) conditions (i.e. to 0oC and under a pressure of 1,013 mbar).
