Why Water Boils In Tall Cups

Summary by Krater

An experiment to see how high water can be lifted in a tube before it boils, demonstrating the formation of a vacuum due to hydrostatic pressure.

From the video

Answers: How high can you lift water in a tube before it boils?

• hydrostatic pressure
• boiling water under vacuum
• water lift height limit
• atmospheric pressure

What it concludes

• The theoretical limit to how high water can be lifted in a tube by a vacuum is 33.8 feet.
• The warmer the water, the less high it can be lifted above the surface before it boils.
• As a water-filled tube is lifted, water pressure drops until it reaches the boiling point of water at that temperature.
