Whoosh bottle Demonstration - chemistry ♦️ [ Ссылка ] | best ever jet bottle
⬛️ A mixture of alcohol and air in a large polycarbonate bottle is ignited. The resulting rapid combustion reaction, often
accompanied by a dramatic ‘ whoosh ’ sound and flames , demonstrates the large amount of chemical energy released in the
combustion of alcohols. the fast combustion of alcohols vapor ,results a high pressure inside the bottle, then the pressure comes out of nozzle in making whoosh sound.
Low-boiling alcohols vaporize readily, and when alcohol is placed in a 5-gallon, small-mouthed jug, it forms a volatile
mixture with the air. A simple match held by the mouth of the jug provides the activation energy needed for the
combustion of the alcohol/air mixture.
Only a small amount of alcohol is used and it quickly vaporizes to a heavier-than-air vapor. The alcohol vapor and air are
all that remain in the bottle ....... the large amount of energy released in the combustion of alcohols.
