How does packaging affect the carbonation of soft drinks
The hypothesis that Coca Cola beverage packed in a glass bottle, a PET bottle and aluminum will have the same amount of dissolved carbon dioxide per 100ml is correct.
Soft drinks like Coca-Cola comes packaged in glass bottles, PET bottles and aluminum cans. They are carbonized by dissolving carbon dioxide at high pressure in the beverages during packaging. The science fair project of the beverage gives it a fizzy taste and causes bubbles to form when the beverage is poured into a glass.
Try to repeat the experiment with different beverages like 7-UP or Pepsi.
The experiment can also be repeated at different temperatures.
