Question

Digestion of food is a physical change.

• A. True
• B. False

Answer 1

The correct option is B False

Physical change:- In a physical change no new substance is formed and the chemical composition of substance remains the same. There are changes in physical properties like shape, size, appearance etc.

Chemical change:- It is a change in which the chemical composition of the substance changes because of the formation of a new substance.

During digestion, large food particles are converted into smaller components that are entirely different in chemical composition and can be readily absorbed into the bloodstream. Hence, digestion of food is a chemical change.
