Gedourain Hand Boiler,Science Rapid Cooling Energy Transfer Experiment Gas liquid Balance for Home Decoration for Ornament

The heat on your hand causes the liquid to boil ,causing the liquid to evaporate into a gas .The expanding gas pushes the liquid upward ,and when you release your hand ,the equilibrium is re established .The gas condenses again into a liquid and flows back to the container below . Boil this liquid at your body temperature ,hold the lower container with your hand ,and observe how the liquid boils and rises through the tube to the upper container . It's a shaped and twisted glass toy with a liquid in it that boils when heat is transferred from your bare hands . It proves the vapour liquid equilibrium ,the colored liquid in the container is a volatile mixture with a boiling point just room temperature . Once leave your hand ,it takes a few minutes for the liquid to cool and return to the container below ,which is a very interesting science toy and a great demonstration of energy transfer ., Manufacturer: Gedourain
