Question

State whether-
Germination of seeds is a chemical change or physical change.

Answer 1

• Chemical change: A change that alters the specific properties of a substance by bringing about a change in its molecular composition, followed by a change in its state, is called a chemical change.
• New substances with entirely new properties are formed.
• A chemical change cannot be easily reversed.
• There is usually a change in weight during a chemical reaction.
• A lot of heat is usually given off or absorbed during a chemical change.

Germination: Germination is the first stage in the transformation of a seed into a seedling. To germinate, all seeds require water, oxygen, and the proper temperature. Germination is a chemical process because in when the seed is germinated then it does not get reversed in the form of a seed.

Therefore, the germination of seeds is a chemical change.
