Question

in an experiment to determine the boiling point of water state reason for the following question the bulb of thermometer should not touch the side of beaker while boiling point while boiling water Puma cystone should be added

Answer 1

The temperature of the water in the beaker varies from that of the beaker. So if thermometer is touched by the beaker,it would dont show exact temperature.

Puma stones are added to boiling water because it would release the temperature in the form of bubbles, if it not added then there will be bursting of water .
