Question

which phrase describes a scientific law?
a. an explanation for why the volume of a gas depends on its temperature
b. a claim that the volume and temperature of a gas are unrelated
c. a prediction of the volume of a gas under special circumstances
d. a statement of how the volume of a gas is related to its temperature

Explanation:

A scientific law describes a natural - occurring relationship or pattern. In the context of gas volume and temperature, a scientific law would state how they are related (such as Charles's Law), rather than explain why (that's a theory), claim they are unrelated, or make a prediction for special circumstances.

Answer:

D. A statement of how the volume of a gas is related to its temperature
