B. Fireworks going off on July 4th

C. Baking soda reacting with vinegar

D. Glass shattering as it hits the floor

Answer 1

Ice melting on a warm day and glass shattering as it hits the floor are both examples of physical changes.

Step-by-step explanation:

Ice melting on a warm day and glass shattering as it hits the floor can both be classified as physical changes.

Physical changes are changes that alter the appearance or state of a substance without changing its chemical composition. In the case of ice melting, the solid ice converts into liquid water due to an increase in temperature. Similarly, when glass shatters, it breaks into smaller pieces, but its chemical composition remains the same.
