This is College Physics Answers with Shaun Dychko. Water will boil when its vapor pressure equals the surrounding atmospheric pressure because that surrounding atmospheric pressure is the maximum possible partial pressure of the water in the air. So, when we look at Table 13.5, we can see that at 70 degrees Celsius, the vapor pressure of water is 3.12 times ten to the four Newtons per square meter and that will equal the atmospheric pressure. So that's what this number is.
