This is a way of modeling nature, enabling us to explain why things happen in the natural world from a scientific point of view. It can be strengthened or weakened but we don't say "proven" or "disproven."

What is a theory? 

400

This is the word for the ratio of the usable energy coming out of a process to the energy that goes into the process. 

What is efficiency?
