Yeast.

A chemical reaction.
It's not the milk alone that makes a cake rise. If the recipe includes milk it probably also contains either baking powder and/or baking soda. This combination of a base (Baking soda or Baking Powder) and an acid (milk) causes a slight chemical reaction which causes the cake to rise.
The flour has a reaction to the other ingreedients and causes the cake to rise.
While baking, the cake expands. This is due to the moisture in the batter heating up, and turning into steam. The steam expands and tries to rise. This causes the cake to puff up and rise, too. When the cake cools, or the steam escapes, the cake will fall as there is nothing to push it and expand it anymore.
Yes. Cakes rise in the center during baking for a few reasons. Flour and yeast can cause it to rise, but also hot air cooks inside the cake. With heat, the air is converted into steam which causes the cake to puff up and rise some more.
Baking powder is a leavening agent, which is what causes the cake to rise. Too little baking powder will cause the cake to be tough and compact, and won't rise as expected.
yes without flour the cake wont rise.
Not every recipe calls for baking soda, but for the ones that do it interacts with the flour to rise and expand the cookies or cake.
baking powder. i have no idea how it works though..
Vinegar is sometimes added to a cake along with baking soda. When the two are mixed together they release gas which causes the cake to rise. If you don't add the vinegar that a cake recipe calls for, your cake won't rise. just letting u kno,,, if u are actually answering these gay questions, u r such a nerd!!! get a life!!
The thermal decomposition of baking powder. Baking powder is also known as sodium bi-carbonate or sodium hydrogen carbonate. When heted it undergoes thermal decomposition., releasing carbon dioxide in thre process. It is this release of CO2 that makes pastry rise when being baked.,
