Which gas helps a cake rise?
Answer and explanation
Correct answer: Carbon dioxide
Baking powder contains sodium hydrogen carbonate and an edible acid. In the presence of moisture and heat, they react to release carbon dioxide gas. Its bubbles spread through the cake batter and make it rise. Water vapour may form on heating, but carbon dioxide is the main gas responsible for raising the cake. Exam tip: Link baking powder and the rising of cakes with carbon dioxide.
