🔍 Key Concepts

• Boiling point vs. ambient temperature – what happens to water when its boiling point is lower than the surrounding temperature? • How absolute pressure (microns) and inches of Hg vacuum relate to each other on the table. • The goal of deep vacuum dehydration is to force any moisture in the system to boil off easily.

💭 Think About

• On the chart, at what pressure does water boil at about 72°F, and what happens to the boiling point as you go to even deeper vacuum (lower microns)? • For the BEST chance of dehydration, do you want the water’s boiling point to be close to ambient temperature, or far below it? Why? • Which option represents the deepest vacuum (lowest absolute pressure), and what boiling temperature does that correspond to on the table?

✅ Before You Answer

• Identify which answer choice corresponds to the lowest absolute pressure in microns. • Check in the chart how far below 72°F the water boiling temperature is at each of the listed microns. • Confirm that the selected choice gives a vacuum level that a deep vacuum pump is realistically designed to reach for proper dehydration.
