Answer #1

We know that chemical change takes place when one substance combines with other to form a new substance or it breaks down into two or more components.

Rusting of a nail, fermenting grapes and tarnishing of a silver bracelet are all examples of chemical change because in each of these a new substance is formed.

Melting ice is a physical change since there is no formation of new product only the state of water changes from solid to liquid.

Therefore, the correct answer is b) melting ice
