WebbFirst, 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. Webb14 apr. 2024 · 263 N High Point Rd , Southport, NC 28461 is a single-family home listed for-sale at $289,900.
