Is boiling water in a vacuum hot?

Water actually boils at a lower temperature if the pressure around it is lowered. This is why if you go to a high altitude location (like many parts of New Mexico), where the atmospheric pressure is lower, water will boil at slightly less than 100 degrees C. In a vacuum chamber, the pressure can be extremely low.
