The Hand Boiler

Materials

.A hand boiler(two glass bulbs that are connected by a thin tube)

.Volatile liquid(should be stored in one of the glass bulbs)

Steps

1. Make sure that you hold the hand boiler on your palm at a certain degree and you will see the volatile transfer from one bulb to the other bulb!

The Principles...

.The boiling point and Heat

-Since the human body has heat and is impact the volatile liquid, the body heat is transferred to the liquid, causing it to boil, thus applying the concept of boiling point by having the liquid changing its state to a gas and evaporating to other glass bulb.

.Charles's Law=describes how gases expand through heat

-Charles's law is applied in the hand boiler with the expansion of the volatile liquid of turning into a gas by the help of the body heat.
