Answer: Engineers can design better bridges because they know how metal changes shape.

Explanation: Physical Properties are those properties which are also regarded as observable because they can be easily seen or observe through naked eyes like melting point etc.

These are those properties which do not change chemical identity of the species.

Thus out of the given options, only physical property is the change of shape of metal.

And the rest one represents the chemical property as chemical property are the one which changes the chemical identity of the substance.
