Final answer:
Cakes fall if taken out from the oven too soon due to insufficient time for the chemical structure to set, resulting in escaping carbon dioxide gas and collapsing of the cake's structure.
Step-by-step explanation:
Cakes may fall if removed from the oven too soon since they have not finished the necessary chemical reactions that give structure to the cake. In the baking process, leavening agents such as yeast or baking powder produce carbon dioxide gas which gets trapped in the batter, causing it to rise and creating air pockets that make the cake fluffy. If a cake is taken out prematurely, the structure may not have set, and the gas can escape, causing the cake to collapse. Additionally, for cakes like pound cake, an equal ratio of sugar to eggs is crucial for the proper chemical balance that also supports the cake's structure.
