Principle of Boiling

point test

A sample is heated gradually in a tube which is immersed in a liquid bath.

The sample tube is held in

close contact with a thermometer and it contains a boiling capillary which is

fused about1 cm above its lower end. Upon approach of the boiling temperature bubbles emerge rapidly

from the lower open end of

the capillary. The boiling temperature is that temperature at which, on

momentary cooling, the string of bubbles stops and liquid suddenly rises in the capillary.
