A chemist is trying to identify a sample of metal that is listed in this table. She passes an electrical current through the sample and finds that, of the metals listed in the table, it’s one of the best conductors. Then she heats the metal to 1000°C, which is the highest temperature her heater allows. The metal doesn’t melt. Which type of metal does the chemist have?



Material Melting Point (°C) Electrical Conductivity Ranking
aluminum 660 3
copper 1085 2
zinc 420 4
silver 962 1
nickel 1455 5



A. aluminum
B. copper
C. zinc
D. silver
E. nickel

Answer :

The correct option is E.

From the information given in the question, we are told that the metal is one of the best conductors and it has melting point that is greater than 1000 degree Celsius. This implies that, options A, C and D can be eliminated, because they have melting points that are less than 1000 degree Celsius. We now have copper and nickel left, but the electrical conductivity of nickel, which is 5 is greater than that of copper, which is 2, although the two of them have melting points that are greater than 1000. Thus, the metal that the chemist was working with is NICKEL.

The type of metal that the chemist has is nickel. That is option E.

What are conductors?

Conductors are those materials, usually metals, that are capable of permitting electric current to pass through them.

The characteristics of a good conductor is that they have high melting points.

From the passage, the chemist heated a metal to about 1000°C and the metal that won't melt at this point is Nickel because it has a melting point of 1455°C.
