Razlaga o poskusu

Zdravo slotecherji, pri biologiji sm dobil poskus za nardit mentos + coca cola ok sem naredil @ dobil štirico ampak mi je manjkala razlaga zakaJ?

Kemiki vi mogoče veste zakaj je to in lepo prosim če bi mi kdo povedal zakaj je to ? vem da je nekaj v vezi z CO2 .

Link, ki ga je dal Peshkeer dovolj dobro razloži poskus na enostaven način, ki bi moral biti razumljiv z osnovnim znanjem angleščine.

Water molecules like to be next to other water molecules, so basically anything that you drop into the soda that disrupts the network of water molecules can act as a growth site for bubbles. And if you have rough candy with a high ratio of surface area to volume, then there's more places for the bubbles to go.

Low surface tension also helps bubbles grow quickly. Measurements showed that the surface tension in water containing the sweetener aspartame is lower than in sugary water, explaining why Diet Coke creates more dramatic fountains than sugary Coke.

Another factor is that the coatings of Mentos contain gum arabic, a surfactant that further reduces surface tension in the liquid. Rough-surfaced mints without the surfactant did not create such large fountains.

Mentos are also fairly dense and sink rapidly, quickly creating bubbles that seed further bubbles as they rise. Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres.

Tukaj je razložena cela znanost o tej reakciji. Prevajat se mi pa ne da :P
