The estimated normal boiling point of isopropyl alcohol is about 81 degrees The boiling point of isopropyl alcohol would be about 101 degrees Celsius

Work Step by Step

81 degrees is about the point at which the liquid has a vapor pressure over 101.3 kPa, and since the substance would have a higher vapor pressure than the external pressure, it will begin to boil If the external pressure is doubled, then the pressure the substance needs to achieve in order to have a higher vapor pressure than external pressure is 202.6 kPa. When Isopropyl alcohol is at 202.6 kPa and begins to boil, it has a temperature of about 101 degrees celsius
