Properties of CO2 Quiz

Properties of CO2 Quiz brings alive the curious facts behind one of nature’s most common yet misunderstood gases. A fun piece of trivia goes back to 1648 when Flemish chemist Jan Baptist van Helmont noticed bubbles forming during fermentation and called the gas “gas sylvestre,” meaning “wild spirit.” That “wild spirit” was carbon dioxide, the same gas that now fizzes in your soda. Over the centuries, scientists studied its role in respiration, drinks, and refrigeration, giving rise to discoveries like the limewater test for CO2 and the meaning of dry ice. This quiz helps you see beyond the bubbles and understand CO2 gas properties through real-world connections and the fascinating chemistry behind them.
