La Sara\u00a0 ens ha presentat un experiment incre\u00efble! <\/span>\u00a0La l\u00e0mpada o llum de lava<\/b>.<\/span><\/p>\n

Per comen\u00e7ar ha barrejat aigua i colorant en un recipient transparent. L\u2019aigua ha quedat tenyida de vermell!<\/span><\/p>\n

Tot seguit ha abocat oli a la mescla. El primer que hem vist \u00e9s que l\u2019aigua i l\u2019oli \u00e9s no es barregen, l\u2019aigua s\u2019enfonsa fins al fons i l\u2019oli puja a la part de dalt. Aix\u00f2 es deu al fet que l\u2019aigua \u00e9s m\u00e9s densa que l\u2019oli.<\/span><\/p>\n

D\u2019altra banda, hem vist que quan s\u2019introdueix la pastilla efervescent, es creen unes bombolles. I \u00e9s que entre els ingredients dels comprimits efervescents es troben el bicarbonat s\u00f2dic i un \u00e0cid org\u00e0nic . A l\u2019entrar en contacte amb l\u2019aigua es forma di\u00f2xid de carboni (CO2), gas que forma petites bombolles ascendents. S\u2019ha\u00a0 generat una reacci\u00f3 qu\u00edmica!<\/span><\/p>\n

I \u00e9s que el gas \u00e9s menys dens que l\u2019aigua i l\u2019oli. Per aix\u00f2 puja. En el trajecte cap a la superf\u00edcie, petites gotes d\u2019aigua tenyides de color ascendeixen impulsades pel di\u00f2xid de carboni. Quan arriben a la superf\u00edcie, el gas s\u2019escapa i les gotes d\u2019aigua que s\u00f3n m\u00e9s denses que l\u2019oli, tornen a caure fins al fons.<\/span><\/p>\n

L\u2019efecte de la lava en aquest experiment finalitza quan la reacci\u00f3 qu\u00edmica acaba.<\/span><\/p>\n

Ens hem quedat amb la boca oberta!<\/span><\/p>\n

Molt b\u00e9 Sara!<\/span><\/p>\n
