At standard pressure (760 mm) water boils at 100C. A vacuum pump is used to reduce the ambient pressure above water under a sealed bell jar. By reducing the pressure, the boiling point is lowered so that the water begins to boil at room temperature. What is the approximate pressure at which water boils at room temperature (22C)?
