Which of the following is a physical change?

The correct answer is Melting of ice.

 Key Points

• The melting of ice is a physical change.
• The change that does not lead to changes in the chemical composition of a substance is termed physical change.
• Physical changes lead to changes in physical properties and are generally reversible in nature. 
• Examples of physical changes are the melting of ice, transition into gas, textural changes, changes in size, shape, color, etc.

Additional Information

• In the case of the melting of ice, only a phase transition takes place, and the chemical composition of ice does not change.
• Chemical changes lead to the transformation in the chemical composition of the substance. Either a new substance is synthesized or a substance is decomposed.
• The setting of milk into curd, the ripening of fruits, and the fermentation of grapes all are examples of chemical changes since the chemical properties of each are changed.
