Question

Identify the appropriate category in which combustion can be categorised.

• A. Physical process
• B. Chemical process
• C. Cyclic process
• D. Biological process

Answer 1

The correct option is B

Chemical process

Combustion refers to the process where a substance burns in the presence of oxygen, giving off heat and light in the process.
The way to recognize a chemical change is to check whether a new substance is being created or not. During combustion, the fuel reacts with oxygen to form some new gases. So, a new substance is definitely formed. So, combustion is a chemical change.
