Multiple Choice

Which of the following statements best distinguishes a law from a theory?

A theory is a mathematical equation, while a law is a detailed description.

A law is a tentative explanation, while a theory is a well-established fact.

A theory is a hypothesis that has been proven, while a law is a hypothesis that has not been tested.

A law describes a natural phenomenon, while a theory explains why the phenomenon occurs.

Verified step by step guidance

Understand the definitions: A scientific law is a statement based on repeated experimental observations that describes some aspect of the world. It predicts the results of certain initial conditions. A theory, on the other hand, is a well-substantiated explanation of some aspect of the natural world that can incorporate laws, hypotheses, and facts.

Identify the characteristics of a law: A law describes what happens under certain conditions but does not explain why it happens. It is often expressed in the form of a mathematical equation or a concise statement.

Identify the characteristics of a theory: A theory provides an explanation for why certain phenomena occur. It is based on a body of evidence and can incorporate various laws and hypotheses.

Evaluate the given options: Compare each statement with the definitions and characteristics of laws and theories. Determine which statement accurately reflects the distinction between a law and a theory.

Select the correct answer: The statement 'A law describes a natural phenomenon, while a theory explains why the phenomenon occurs' best distinguishes a law from a theory, as it aligns with the definitions and characteristics discussed.
