Question

Classify the following changes into physical change and chemical change:

Melting of ice.

Answer 1

Chemical change: It is a type of change in which there is a change in the chemical properties of the substance and a new substance is formed.

• It is a type of irreversible change.
• Rusting iron is an example of chemical change.

Physical change: It is a type of change in which there is no change in the chemical properties of the substance and no new substance is formed.

• It can be a reversible change.
• Melting and freezing of ice is a Physical change.

Melting of ice:

• Melting of ice will result in the formation of water and both water and ice have the same composition.
• It is also a type of reversible reaction.
• As only the physical state of matter is changing so it comes under a physical change.

Therefore, the melting of ice is a type of physical change.
