Boiling point The temperature at which the liquid–gas phase adjust occurs.
SublimationThe change of a substance directly from the solid come the gas step without passing with a fluid phase.
Density (g cm−3)Density is the fixed of a problem that would fill 1 cm3 at room temperature.
Relative atom massThe massive of one atom loved one to that of carbon-12. This is about the sum of the number of protons and also neutrons in the nucleus. Where more than one isotope exists, the value offered is the abundance weighted average.
