Formula for calculating boiling point
WebPentane has five carbons, one, two, three, four, five, so five carbons for pentane. And pentane has a boiling point of 36 degrees Celsius. Hexane has six carbons, one, two, three, four, five, and six. So six carbons, and a higher boiling point, of 69 degrees C. Let's draw in another molecule of pentane right here. WebEquation. The Antoine equation is = +. where p is the vapor pressure, T is temperature (in °C or in K according to the value of C) and A, B and C are component-specific constants.. The simplified form with C set to zero: = is the August equation, after the German physicist Ernst Ferdinand August (1795–1870). The August equation describes a linear …
