Is raisins and fizzy drink a physical reaction?

No, the combination of raisins and fizzy drinks is not a physical reaction. Here's why:

* Physical reactions involve changes in physical properties, not chemical composition.

* Raisins in fizzy drinks are an example of a physical change. The raisins absorb the carbon dioxide gas from the fizzy drink, causing them to expand and dance around. This is a change in the physical state of the raisins (they become larger), but their chemical composition remains the same.

Here's a breakdown:

* Fizzy drinks: The bubbles in fizzy drinks are carbon dioxide gas dissolved in the liquid.

* Raisins: Raisins are dried grapes.

* What happens: When you put raisins in a fizzy drink, the carbon dioxide gas in the drink is attracted to the raisins and dissolves into them. This causes the raisins to swell up. As the gas bubbles form in the raisins, they rise to the surface of the liquid, causing the raisins to dance.
