Summary
| Description |
English: Solid alcohol – preparing it and burning
- When iso-propanol (or other liquid alcohol) is poured in Dewar vessel containing liquid nitrogen, a dense fog is obtained. The iso-propanol and other lower alcohols tend to evaporate easily. The alcoholic vapors in contact with the liquid nitrogen, condense and a thick fog appears. The alcohol that is poured in the nitrogen containing vessel freezes (freezing point of iso-propanol is –89 °C). The solid alcohol can be ignited and at the beginning it burns with almost colorless flame. Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Македонски: Добивање и горење на цврст алкохол
- Кога изопропанол (или друг течен алкохол) ќе се стави во Дјуаров сад во кој има течен азот се создава густа магла. Изопропанолот, како и другите пониски алкохоли, лесно испарува. Алкохолните пари во контакт со течниот азот се кондензираат и се создава густа магла. Алкохолот истурен во садот со течен азот, замрзнува (т.т. на изопропанол е –89 °C). Цврстиот изопропанол, запален гори со, на почетокот, речиси безбоен пламен. Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје. |
