Question

Почему когда кидаешь ментос в колу , кола шипит очень сильно?

Answer 1

Потому что кока-кола содержит очень много кислот, что может растворит монету. А ментос, как и другие вещеста подобные ему, имеют способность щипеть в житкости (пример - аспирин).

Answer 2

Why does Coke fizz so much when you drop Mentos into it?

When you drop Mentos into Coke, it causes a dramatic fizzing reaction. This reaction occurs due to a combination of factors, including the physical structure of Mentos and the carbonation in Coke.

The physical structure of Mentos: Mentos candies have a rough surface with numerous tiny pits and crevices. These pits and crevices provide nucleation sites for the carbon dioxide gas bubbles in the Coke to form and rapidly escape. The rough surface of Mentos provides a large surface area for the gas bubbles to form, leading to a more intense reaction.

Carbonation in Coke: Coke is a carbonated beverage, meaning it contains dissolved carbon dioxide gas. The carbon dioxide is added to the beverage under pressure, which allows it to dissolve in the liquid. When you open a bottle of Coke, the pressure is released, and some of the carbon dioxide comes out of solution in the form of bubbles. These bubbles are what give Coke its characteristic fizziness.

When you drop Mentos into Coke, the rough surface of the Mentos candies disrupts the surface tension of the liquid, causing an even greater release of carbon dioxide bubbles. The carbon dioxide gas rapidly escapes from the liquid, resulting in a fountain-like eruption of foam and fizz.

It's important to note that the reaction between Mentos and Coke is not exclusive to Coke. Similar reactions can occur with other carbonated beverages, although the intensity of the reaction may vary depending on the specific properties of the beverage.

In summary, the intense fizzing reaction that occurs when you drop Mentos into Coke is due to the physical structure of Mentos providing nucleation sites for the carbon dioxide bubbles to form and the carbonation in Coke causing the rapid release of the gas bubbles.
