What causers fizzy drinks to go flat?

Answer 1

Sparkling waters, wines and, of course, soda pops fizz because of the carbon dioxide dissolved, at high pressures and low temperatures, in every can and bottle. Carbonation adds a weak acid that gives your Coca-Cola a little tang while acting as a preservative, as well.

When you pop the top, the pressure inside the can decreases, causing the CO2 to convert to gas and escape inbubbles. Let a can sit long enough before sipping and you will notice not only the lack of bubbly fizz but also the absence of the carbonic flavor.

Beverage chemistry may be the largest single market for carbon dioxide, but it's not the only one. Solid CO2 refrigerates better than ice from H20, and this solid carbon dioxide, or dry ice, is used to freeze foods.

Answer 2

Carbon dioxide is the gas that makes drinks fizzy or carbonated. When you first open a drink, you twist to break the seal so even if you put the cap back on tightly, over time the carbon dioxide gas that is still in the bottle slowly seeps out and you are left with just flavored water.

Answer 3

if its container is opened, yes. if not, no. just like on earth.

Answer 4

The fizz is due to dissolved carbon dioxide. When the drink container is opened, the extra pressure is lost and the CO2 is gradually lost into the surrounding air. No dissolved CO2 = no fizz.

Answer 5

it goes lighter
