Summary[edit]
Description50. Магична лажичка (Вудова легура).ogg |
English: Magic spoon – Wood’s alloy
- By melting of bismuth, thin, lead and cadmium in a certain ratio, an alloy called Wood’s alloy is obtained. This alloy has a melting temperature of 70 °С, that is remarkably lower than the melting temperature of its components separately (bismuth 272 °С, tin 232 °С, lead 327 °С and cadmium 321 °С). When a spoon made out of the alloy composed of these metals is placed in a cup with hot water, it melts very fast. Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Македонски: Магична лажичка – Вудова легура
- Со топење на бизмутот, калајот, оловото и кадмиумот во определен сооднос се добива т.н. Вудова легура која има температура на топење од 70 °С што е значително пониска од температурата на топење на секој од металите одделно (бизмут 272 °С, калај 232 °С, олово 327 °С и кадмиум 321 °С). Направената лажичка од оваа легура, ставeна во чаша со топла вода, веднаш се топи. Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје. |
