Steel
water
aluminum
Think about the three words listed here. Which word could be added as the title of this list of words to tell how these words are related?

A) conductors
B) heat
C) insulators
D) metals

A) conductors

Explanation:

Correct

A) conductors (for electricity)

Although pure water is actually an insulator, the question does not say "pure" water. Water usually has other substances in it that are not H₂O, like salt and dissolved minerals, making it a conductor. Aluminum and steel are both metals, which are conductors.

Incorrect

B) heat :   Steel and aluminum are both metals, which heat up and cool down quickly. Water is slow to heat up and cool down, which is why the temperature of cities near water has lower ranges.

C) insulators :   The metals steel and aluminum are not insulators. Pure water is an insulator, but water is usually not pure because it contains other substances.

D) metals:   Although steel and aluminum are metals, water is not considered a metal (but it may contain very small metallic substances in it).

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
