El procediment de l’experiment \u00e9s el seg\u00fcent:<\/p>\n

    \n
  1. Tirem aproximadament dues cullerades d’alcohol a una ampolla.<\/li>\n
  2. Movem l’ampolla per assegurar la distribuci\u00f3 de l’alcohol per la base i les parets internes.<\/li>\n
  3. Tanquem herm\u00e8ticament l’ampolla amb el tap.<\/li>\n
  4. Perforem el tap ( veure imatge )\u00a0 amb l’agulla de la bomba d’aire.<\/li>\n
  5. Inflem l’ampolla amb la bomba d’aire fins assolir la pressi\u00f3 m\u00e0xima.<\/li>\n
  6. Retirem el tap r\u00e0pidament.<\/li>\n<\/ol>\n

    Resultat: Es genera un n\u00favol a l’interior de l’ampolla. Podem repetir aquest proc\u00e9s diverses vegades sense necessitat de substituir l’alcohol.<\/p>\n

    Explicaci\u00f3:<\/p>\n

    Mitjan\u00e7ant la bomba d’aire, augmentem la pressi\u00f3 a l’interior de l’ampolla (les part\u00edcules es comprimeixen i col\u00b7lisionen entre si), provocant un augment de la temperatura. Aix\u00f2 fa que l’alcohol passi a l’estat gas\u00f3s. En retirar el tap, l’aire surt r\u00e0pidament, disminuint la pressi\u00f3 i la temperatura de manera abrupta. Aquest canvi provoca que l’alcohol en estat gas\u00f3s es condensi, transformant-se en min\u00fascules gotes l\u00edquides i creant el n\u00favol. Espectacular!!!<\/p>\n

    Us deixem algunes fotos:<\/p>\n
