Answer

Brief Explanations:

Physical changes do not change the chemical composition of a substance, while chemical reactions result in new substances with different chemical properties. Wax melting, grinding wheat, and alloying copper with gold are physical changes as they only change the physical state or form. Seed - growth, burning sugar, and silver - tarnishing involve chemical reactions as new substances are formed.

Answer:

Physical Change: wax melting from applied heat, grinding wheat to make flour, adding copper with gold to make jewelry Chemical Reaction: growth of a seed into a seedling, making caramel by burning sugar, tarnishing of silver
