CRC 85th edition states 3825 is carbon's sublimation point at STP, but in view 
of the Sun's low atmospheric pressure, is this the proper boiling/depostion 
point?  NASA info referenced temperatures as low as 3700 degrees K in 
sunspots.  My thoughts are: that carbon, like H20 is deep space, would assume 
a solid state at its deposition point, regardless of atmospheric pressure. 
Thanks for your time.          Karl Bertram
