Summary
| Description |
An experiment that demonstrates the large amount of energy released upon combustion of ethanol. A mixture of alcohol (in this case, ethanol) vapour and air in a large plastic bottle with a small neck is ignited, resulting in a large blue flame and a 'whoosh' sound. This is an example of exothermic reaction and demonstrates the large amount of energy released in the combustion of alcohols. The reaction of burning of ethanol is represented by the following chemical equation:
Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia. There are no spoken or printed words in this video, so it can be used in any language. |
