I believe I seen on google if you go to Mather
Pressure is proportional to kinetic energy per unit volume, while temperature is proportional to kinetic energy per particle. ... A gas can be at high temperature and low pressure if it has low number density; likewise, a gas can be at low temperature and high pressure if it has high number density.
This would prove that gold is an <em>element</em>. No matter how far down you
examine it, you never find any particles of anything except gold.
An example of a different case is salt.
-- Imagine you had a block of salt and decided to cut it in half.
-- If you repeated this process, then eventually, at some point, you'd have
a tiny particle of salt in front of you, just like before. BUT ...
-- Just as you were getting ready to cut this one in half, you'd notice that this
particle of salt is different. It's one atom of sodium stuck to one atom of chlorine,
and if you cut it in half, you would not have ANY salt. <span />
This would prove that salt is a <em><u>compound</u></em>, made of atoms of two or more elements.
