Yeast and sugar are added to champagne to give the sparkle of carbonation.Under what conditions is carbon dioxide gas most soluble?

Question

Quizplus · Accepted Answer

Carbon dioxide gas is most soluble under low temperature and high pressure. Adding yeast and sugar to champagne creates a fermentation process that produces carbon dioxide gas, which dissolves in the liquid under high pressure in the bottle. When a champagne bottle is opened, the sudden release of pressure causes the dissolved carbon dioxide to rapidly escape, creating the bubbles and sparkle.
