Asked by Christian

According to the scientific observation that energy is conserved in a "closed system,” no machine can do work on its surrounding environment forever. This observation has been made over and over again in all sciences, and no example has been found that disproves the fact of conservation of energy.

The fact that energy is always conserved in a closed system is what type of scientific statement?

a law
a theory
an inquiry
a hypothesis

a law

The conservation of energy is a scientific law — a descriptive statement, often mathematical, based on repeated observations that consistently hold (whereas a theory explains why those observations occur).
