Question

Elsa loves ice creams and makes it at home.One day she invited her friends for an ice cream party but unfortunately there was a power cut for 3 hours and the ice cream she prepared melted down.Melting of ice cream is what type of a change?

• A. Chemical change
• B. Physical change
• C. Both physical and chemical change
• D. Cannot be determined

Answer 1

The correct option is B

Physical change

Physical change is a change in which the appearance of the substance changes but not the characteristics of the substance.Here the ice cream which has melted has changed physically and cannot be served to the friends of Elsa.But the taste of ice cream is same as there is no change in the chemical composition of the ice cream; also the ice cream can be served back when it is frozen again.Therefore it is only a physical change.
