Answer: A hypothesis is a limited explanation of something, a theory is a deep explanation of something backed up by evidence, and a law is a proven statement about an something.
Explanation:
A theory is a supposition or a group of linked ideas which tries to explain some phenomenon. It provides a framework for explaining observations based on assumptions but also backed up by evidence.
A hypothesis is a proposed explanation or prediction of an observation and that can be tested through an experimentation. It is more than a wild guess of a phenomenon but less than a well-established theory. For example, in science, a hypothesis is part of the scientific method. But experiments may disprove a hypothesis, but can never entirely prove.
A law in science is a generalized rule to explain an observation of a phenomenon in the form of a statement. It implies a cause and effect between the different observations and those laws must always apply under the same conditions.
So a hypothesis is a limited explanation of something, a theory is a deep explanation of something backed up by evidence, and a law is a proven statement about an something.
