Rho is the mass per unit volume of earth s atmosphere air density like air pressure decreases with increasing altitude. Its monatomic form h is the most abundant chemical substance in the universe constituting roughly 75 of all baryonic mass.

The ratio of density of iron at room temperature to that at 900 c assuming molar mass and atomic radii of iron remains constant with temperature is. For bcc 4r 1 73 a a 4 r 1 73 1 for fcc 4 r 1 4 a a 4 r 1 4 2. If we neglect the temperature dependence of the radius of the iron atom on the grounds that it is negligible we can calculate the density of fcc iron. Iron is the cheapest and one of the most abundant of all metals comprising nearly 5 6 of the earth s crust and nearly all of the earth s core.
