Do hypotheses become laws?

If a hypothesis becomes well established, is it a law or a theory?

A law is just a description of a pattern in the data.

A theory is an explanation for the pattern. The law shows what happens, without explanation.

A theory explains how it happens, often by using using an analogy or metaphor.

So whether a hypothesis that becomes well established becomes a law or a theory depends on whether it tells you what happens, or it tells you how something happens.
