Slider A is currently locked as the pivot. Slider B is currently locked as the pivot. Slider C is currently locked as the pivot.
A Observed Boiling Point at pressure P (mmHg)
B Boiling Point Corrected at 1 atm (760 mmHg)
C Pressure "P" (mmHg)
1 atm = 760 mmHg

 

To find a boiling point under a set vaccuum

Chart B - Enter your known boiling point (or simply slide the bar) and click the lock.

Chart C - Select the pressure you are working at(Torr or mmHg) and click the lock.

To find a corrected boiling point @760mm

Chart A - Enter observed boiling point (or simply slide the bar) and click the lock.

Chart C - Select the pressure you are working at(Torr or mmHg) and click the lock.
