What is the difference between a scientific theory and a scientific law?

• A theory is a well-tested range of representations and a law is a concrete physical representation.

• A theory is a well-tested range of observations of why something works and a law is a well-tested concrete explanation how things work

• A theory is a well-tested range of observations of how something works and a law is a well-tested concrete explanation of why things work

• A theory is a hypothesis that is yet to be proven false and a law is a hypothesis that will always be true.
