✔ 最佳答案
因為可口可樂其實是糖水加二氧化碳,而二氧化碳溶於水中會變成(碳酸),令溶液變成酸性過多的碳酸會在打開了蓋子後變成二氧化碳,然後擴散到周圍的空間中,使酸性下降
然而,糖水的份量没有改變,但酸性卻下降了
可口可樂因而變甜

It is only a feeling. There is no change for the composition of Coca Cola.
Because after opening for one hour, Coca Cola will release nearly all the Carbon Dioxide and the temperature will be higher than before in the refrigerator. So you FEEL more sweet than before.

coca cola 的原料就是用糖醬和carbonate 混合而成。你沒有看成份表 -- 糖(carbonhydrate)
的成份很高。Coca cola 根本就是糖水。
