Boiling point of water in a closed container

  1. Mar 3, 2010 #1
    Hi all, for a closed container with water under pressure in it, let's say GAUGE PRESSURE of the container is 101 kPa, what will the boiling point of water in that vessel be? Will it be 100 deg C, or will it be 120 deg C because the ABSOLUTE PRESSURE of the water in that vessel is 202kPa? Basically I wanted to see if boiling point is dependent on ABSOLUTE PRESSURE or GAUGE PRESSURE!

    Well, hopefully you know that when the absolute pressure is 1 atm (gauge pressure = 0, relative to 1 atm), the boiling point is 100 C.
