"Whereupon are the foundations thereof fastened? or who laid the cornerstone thereof."—Job xxxviii.
804. Why does boiled water taste flat and insipid?
Because the carbonic acid has been driven off by boiling.
805. Why does beer which has been standing in a glass taste flat?
Because its carbonic acid has escaped as carbonic acid gas.
806. Why, when we look into a glass of champagne, do we see bubbles spontaneously appear at the bottom, and then rise to the top?
Because, in the places where the bubbles are formed, the liquid carbonic acid is evolving into carbonic acid gas.
