Carbonated water or Soda water is water that has been infused with carbon dioxide gas under pressure. This produces a bubbly drink that's also known as sparkling water, club soda, soda water, seltzer water and fizzy water. With the exception of seltzer water, they usually have salt added to improve the taste.
The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.
