School In 1643, two disciples of Galileo, Evangelista Torricelli and Vincenzo Viviani(1622-1703), resume the experiment using mercury, which is about 14 times denser than water. They had the knowledge of experience Berti. Torricelli found that the mercuric would rise 14 times higher than water. The experiment was entrusted by the Torricelli Viviani. Viviani a tube filled with mercury and covered one of its ends. Then sealed with one of his fingers the other end of the tube and capsized a bowl full of mercury. Interestingly, the mercury tube down to the basin leaving a column of 76 cm in the tube. In the remainder of the tube was vacuum. What would be the explanation of this phenomenon? Torricelli concluded that the air layers exert with his weight on the real pressure mercury basin, and this pressure maintained in suspension mercury column in the tube. That is why, he said, not because of a hypothetical vacuum resistance limit, the height of water column was limited to ten meters. And showing proved that the height of the mercury column (14 times more dense than water) corresponded to 1/14 of the height of the water column. Moreover, slight variations noted everyday the height of the mercury column, and concluded that they were due to variations in atmospheric pressure. Torricelli had just demonstrate the weight of air and inventing the barometer, which allowsmeasure it. But still, got the vacuum in an enclosure, which proved that nature had no horror of it! Reporting their experience Torricelli asserted that the mercury was sustained by an external force to the tube. Above the mercury column was an empty space, Torricelli said. This gap is known as vacuum Torricellano. furiously, and was accurate and Perier repeat the experi- right at the bottom and at the top finally managed derru- Unlike apregoaque nature have higher than the top of a in short they demonstramuito nosno more air over the top of the foot that mountain.

Škola U 1643, dvije učenici Galilea, Evangelista Torricelli i Vincenzo Viviani(1622-1703), nastaviti eksperiment koristeći živu, što je oko 14 puta gušća od vode. Oni su imali znanje iskustva Berti. Torricelli je utvrdio da je živa bi porasti 14 puta veća od vode. Eksperiment je povjerena od strane Torricelli Viviani. Viviani cijevi ispunjen žive i pokriven jedan od svojih ciljeva. Zatim zapečaćena s jednim od svojih prstiju drugom kraju cijevi i prevrnuo zdjelu punu žive. Zanimljivo, živa cijevi do bazena ostavljajući kolone od 76 cm u cijev. U preostalom dijelu cijevi je vakuum. Što će biti objašnjenje ovog fenomena? Torricelli je zaključio da su slojeva zraka napregnuti svom svojom težinom na pravi tlaka živa bazena, a taj pritisak održava u suspenziji stupca žive u cijevi. Zato je, kazao je, ne zbog hipotetske vakuum otpornosti granice, visina vodenog stupca je ograničen na deset metara. I pokazuje dokazao da visina stupca žive (14 puta gušća od vode) odgovarao na 1/14 od visine vodenog stupca. Osim toga, male varijacije istaknuo svakodnevno visina stupca žive, te je zaključio da su s obzirom na varijacije u atmosferskog tlaka. Torricelli je upravo pokazuju težinu zraka i izmišljanje barometar, koji omogućujemjeriti. Ali ipak, dobio je vakuum u ograđenom prostoru, što se pokazalo da priroda nije imao užas njega!(Suparnika, M., 1997, str. 18.) Izvješćivanje svoje iskustvo Torricelli ustvrdio da je živa je nošena vanjske sile na cijevi. Iznad živa stupac bio prazan prostor, Torricelli rekao. Taj jaz je poznat kao vakuum Torricellano. bijesno, te je bio precizan i Perier ponovite is- desno na dnu i na vrhu napokon derru- Za razliku od apregoaque prirodi imaju veći od vrha u kratko oni demonstramuito nosno više zraka preko vrha stopala koji Planina.
