Em 1643, Evangelista Torricelli realizou um experimento com o qual mediu a press\u00e3o atmosf\u00e9rica terrestre ao n\u00edvel do mar. Encheu com merc\u00fario um tubo de aproximadamente 1 m de comprimento, fechou-o e, invertendo o tubo, mergulhou sua extremidade em outro recipiente tamb\u00e9m contendo merc\u00fario. Ap\u00f3s a abertura da extremidade do tubo, o merc\u00fario desceu at\u00e9 estabilizar-se \u00e0 altura de 76 cm.<\/b><\/span><\/span><\/span><\/span><\/p>\n

Os\u00a0<\/b><\/span><\/span>estudos de hidrost\u00e1tica\u00a0<\/b><\/span><\/span>de Arquimedes (288\u2013212 a.C.) o\u00a0<\/b><\/span><\/span>levaram a conclus\u00e3o de que corpos imersos em um liquido, total ou parcialmente, sofrem a a\u00e7\u00e3o de uma forca vertical, voltada para cima, denominada empuxo.<\/b><\/span><\/span><\/span><\/span><\/p>\n

Devido\u00a0<\/b><\/span><\/span>\u00e0s caracter\u00edsticas dessa forca, o empuxo op\u00f5e-se a a\u00e7\u00e3o do peso, que atua sobre todos os corpos.<\/b><\/span><\/span><\/span><\/span><\/p>\n

<\/p>\n

Quando um\u00a0<\/b><\/span><\/span>corpo se encontra totalmente submerso, a rela\u00e7\u00e3o entre a forca peso e a forca de empuxo reduz-se a um confronto entre densidades: a do corpo e a do liquido no qual ele se encontra submerso.<\/b><\/span><\/span><\/span><\/span><\/p>\n

Para obter o empuxo necess\u00e1rio, alguns peixes \u00f3sseos possuem um \u00f3rg\u00e3o denominado bexiga natat\u00f3ria que os auxilia no controle de sua flutua\u00e7\u00e3o sem o auxilio de suas nadadeiras, devido a presen\u00e7a de g\u00e1s em seu interior.<\/b><\/span><\/span><\/span><\/span><\/p>\n

Quando um\u00a0<\/b><\/span><\/span>peixe desse tipo apresenta problemas na bexiga natat\u00f3ria\u00a0<\/b><\/span><\/span>e\u00a0<\/b><\/span><\/span>n\u00e3o consegue manter o g\u00e1s aprisionado,<\/b><\/span><\/span>\u00a0<\/b><\/span><\/span>ter\u00e1 dificuldades em manter-se a uma mesma profundidade\u00a0<\/b><\/span><\/span>e tamb\u00e9m em\u00a0<\/b><\/span><\/span>aproximar-se da superf\u00edcie, tendendo a ficar no fundo.<\/b><\/span><\/span><\/span><\/span><\/p>\n
