Emisferi di Magdeburgo
Summary
[edit]Description00164 Emisferi di Magdeburgo.jpg |
Italiano: Lo strumento è composto da due emisferi di metallo di diametro di 12cm che aderiscono perfettamente grazie ad una guarnizione di gomma che garantisce la perfetta tenuta impedendo il passaggio di aria dall’esterno verso l’interno. Nell’emisfero inferiore è situato un rubinetto che permette il collegamento dello strumento ad una pompa aspirante (rubinetto aperto) e il successivo isolamento (rubinetto chiuso), mentre l’emisfero superiore è dotato di un gancio ad anello per consentire una presa comoda agli sperimentatori. Strumento creato da Otto von Guericke per dimostrare l'esistenza del vuoto e gli effetti della pressione atmosferica. Fonte: Liceo Scientifico "Ulisse Dini" |
