Determine whether the statement is true or false, and why. “If a theory becomes supported by evidence, it can become a law.” A.
tensa zangetsu [6.8K]

The given statement is False, it should read, "A theory and a law are already both supported by evidence and are equal, but they have different functions."

In the scientific method, a "Theory" and a "Law" are already both supported by evidence, but they serve different purposes.

The role of "Theory" in the scientific method is to provide a justification for the data collected through observations and results. As more data is gathered, it may be altered, enhanced, or even dismissed. While a "law" typically refers to an observed natural event that is true no matter how it is tested. It doesn't explain why the incident or event actually happened.
