*Right* is a concept which exists only in the minds of *people*.
There are always different ideas of *right* held by different groups of
people...


Copper anneals at dull red heat and melts within the range of cherry red
heat. Presuming that melting the tube is an undesirable result, the right
method is set by physics and is not simply an opinion.


The ?laws? of science, including physics, are *only* an agreement by
scientists in general that this is the best idea of reality we have at the
moment. Popper IIRC believes that all "Scientific laws" will be
overturned or drastically modified within 200 years of formulation.
http://en.wikipedia.org/wiki/Scientific_law
A physical law, scientific law, or a law of nature is a scientific

generalization based on empirical observations. They are conclusions or
hypotheses which have been confirmed by repeated scientific experiments
over many years, and which have become accepted universally within the
scientific community.
Also http://en.wikipedia.org/wiki/Karl_Popper

A classic example of laws being found wrong is Newton's Laws of Motion,
http://en.wikipedia.org/wiki/Newton's_laws_of_motion which still describe
motion of most bodies in an *Engineering* sense perfectly. However they
fail on an atomic scale when Quantum physics describes atomic and sub
atomic particles better. Also they fail on an astronomical scale where
Einstein's theories of relativity give better results
