Question

which scenario is an example of a physical change?
o wood is burned in a campfire and is turned into ash and smoke.
o a piece of metal is left in the rain and forms rust.
o lead is melted into a liquid to form pellets.
o yeast turns sugar into energy, water, and carbon dioxide gas.

Explanation:

A physical change is a change in the form or state of matter without a change in its chemical composition. Burning wood, metal rusting, and yeast - sugar reaction are chemical changes as new substances are formed. Melting lead only changes its state from solid to liquid without altering its chemical identity.

Answer:

Lead is melted into a liquid to form pellets.
