Pressure increases and, on the average, this is causative of the increase in temperature and also the density.. ,
Explanation:
On the average, the gradients for temperature, pressure and density
are all positive with respect to the depth.
From surface to center:
Temperature range is about
Pressure range is nearly 101325 Pa-350 mega Pa.
Density range is nearly 1+ g/cc (sea water) - 13.1 g/cc (solid
iron/nickel)
At the extreme central pressure, iron is back to the solid form,
despite that temperature (#7200^0C) is more than the Sun/s surface
temperature (
#1 Pa = 1 Newton/(meter)62 and atmospheric pressure at mean
sea level = 101325 Pa (Pa to honor Pascal)
