Boiling Range: The spread of temperatures, usually expressed in degrees
Fahrenheit, over which oil starts to boil or distill vapors and proceeds to
complete evaporation. Boiling range is determined by ASTM test procedures
for specic petroleum products.
Boiling Temperature: Temperature at which steam bubbles begin to appear
within a liquid. When the ...
