Interpretation:
Whether melting of an ice cream is a physical or a chemical change needs to be explained.
Concept introduction:
Physical changes involves the change in substances without undergoing a change in chemical composition. Chemical changes involves the change in the composition of the substance as the substances break and combine to form a new
Answer to Problem 88A
Melting of an ice cream is a physical change as the liquid ice-cream solidifies again with the same chemical composition.
Explanation of Solution
When eating ice-cream in a hot day melts the ice-cream. The change in the melting of an ice-cream is the physical change as the composition remain same
Ice cream is a mixture of air, water, milkfat, nonfat milk solids, sweeteners, stabilizers, emulsifiers and flavors all these substances when melts doesn’t lose their chemical composition. Hence the change is considered to be physical change.
Melting of an ice cream is a physical change as the liquid ice-cream solidifies again with the same chemical composition.
