Problem 21CQ

Why does a beaker of 40.0ºC water placed in a vacuum chamber start to boil as the chamber is evacuated (air is pumped out of the chamber)? At what pressure does the boiling begin? Would food cook any faster in such a beaker?

Step-by-Step Solution:
Step 1 of 3

Solution 21CQ

Boiling temperature is directly proportional to the pressure. Lower the pressure, lower the boiling temperature. The pressure inside the vacuum chamber is very low; this pressure is about zero atm. Therefore, the boiling temperature of the water decreases in the vacuum chamber.

Since the pressure inside the vacuum chamber is about 0 atm. The water inside the vacuum chamber boils at 0 atm.

The water inside the vacuum chamber boils comparatively at low temperature. Therefore the time of cooking food is increases.
