Answer 2

Explanation:

When a candle burns, both physical and chemical changes take place.

Physical change → Melting of wax

Chemical change → Burning of wax

Eating of food is another example where both physical and chemical changes occur simultaneously.

Physical change → Breaking down of larger food particles into smaller particles

Chemical change → Digestion of food
