WebFirst, let's say we have a compound with a boiling point of 100oC at 1mm Hg pressure. What is the boiling point at 760mm Hg? To do this we need to draw a line from 100oC on scale A (left side, observed boiling point) to 1.0 mm Hg on scale C (right side, pressure "P" mm). We can then read off the boiling point at 760 mm on line B, it is about 280oC. WebEmbed this widget ». Added Aug 1, 2010 by Hugo in Materials.
