All theories are hypotheses but not all hyptheses are theories .francis is wants to know if a specific hypothesis he is researching is a theory. which describes how francis would know the hypothesis is a theory

Hypothesis is speculation, while theory is an explanation. That way, Francis will know that the hypothesis is a theory if a given hypothesis is tested and the test result explains a scientific phenomenon.

Explanation:

The hypotheses are conjectures, speculations, predictions about a certain phenomenon in nature and how it behaves. Hypotheses must be tested, which is usually done through experiments.

Theories are well-founded explanations for describing events that occur in nature. They involve exhaustively tested hypotheses, facts and laws.

A theory may sound like a definitive explanation, but it can be overturned over the years.

If the hypothesis, after being tested, can satisfactorily explain a specific phenomenon, we can consider this hypothesis to be a theory.
