- The disease caused due to the presence of large number of microorganisms in the food or due to the presence of toxic substances in the food formed by the action of microorganisms is called food poisoning.
- The chemicals used to check the growth of microorganisms are called preservatives. The food materials like milk, fruits, vegetables, meat, fish, cooked food, etc. get spoiled easily as they contain a lot of water due to which microorganisms can grow on them easily. We can prevent such food items by the proper methods of food preservation. The process in which the food materials are given a suitable physical or chemical treatment to prevent their spoilage is called food preservation.

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.
The definition of combustion means burning, or a chemical change that produces heat and light. An example of combustion is an explosion. An example of combustion is oxidation accompanied by heat and light. The products of a complete combustion reaction include carbon dioxide (CO2) and water vapor (H2O).
