b)
Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. When you mix wet and dry ingredients, baking powder activates instantly, enlarging bubbles in the batter and making it rise. But if you don't work quickly and get the batter into the oven in just a few minutes, those bubbles will rise right out of the batter and into the air.
c)
Air can be added to food mechanically using whisking, sieving, creaming, beating, rubbing in, rolling and folding. During creaming (where fat and sugar are creamed together), air is added to the mixture, and is enclosed by the fat.
