Principle

When the air pressure above a watersurface is reduced, the water begins to boil at a certain temperature. The temperature of the water is hereby reduced and further evacuation can finally bring it to 0 °C and even lower.

Benefits

• Data logging via tablet possible.
• For both demonstration and student experiments

Tasks

Determine the temperature curve of water during pumping.
