The liquid wax is drawn to the tip of the wick which is inside the flame and the liquid is changed into the state of matter that is gas.
(If the molecules of air at normal temperature and pressure were arranged in cubical order, the edge of each cube would be about 2.9 X I o - ' cms.; the average diameter of a molecule in air is 2.8X Io - 8 cms.) Further and very important evidence as to the nature of the gaseous state of matter is provided by the experiments of Joule and Kelvin.
These two simplifying facts bring the properties of the gaseous state of matter within the range of mathematical treatment.
And, under certain circumstances, the quark-gluon plasma (the state of matter in the universe before it cooled) might be recreated.
They will study the phenomenon of quark color superconductivity, a new state of matter thought to occur in the center of neutron stars.
