Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal. b. he is determining chemical properties that are sufficient to identify the metal. c. he is determining physical properties that are insufficient to identify the metal. d. he is determining chemical properties that are insufficient to identify the metal.

 A. He is determining physical properties that are sufficient to identify the metal.

Chemical properties are properties which are determined by altering the chemical composition of a substance.

Physical properties are properties which are determined without altering the chemical composition of a substance.

Physical properties such as density, electrical conductivity, and melting point are sufficient to identify a metal as these properties are independent of the  amount of substance being examined.

These properties are known as intensive properties and are used  to identify a substance by comparing the obtained values with standard values.

i'm assuming that the correct answer is indeed the first one/ "a"..
