How does baking powder help food rise?
Answer and explanation
Correct answer: By producing carbon dioxide
Baking powder contains sodium hydrogen carbonate along with a mild edible acid. When the mixture becomes moist and is heated, they react and release carbon dioxide gas. The gas expands and gets trapped as bubbles in the batter or dough, increasing its volume and making the food light and spongy. Hydrogen, chlorine, and nitrogen are not the gases responsible for this rising effect, so option A is correct.
