When a cake is baked it changes its physical appearance and is thus said to undergo a physical change.
However there are many concurrent chemical changes:
- sugars caramelize
- proteins coagulate
- leavening agents (baking soda etc.) release carbon dioxide
- starches, oils and fats oxidize

What is the difference between chemical change and a physical change?
a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake
What does physical and chemical mean in science?
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
What are three examples for chemical change?
Burning, rusting, and production of gas are examples of chemical changes.

What is the science behind a cake rising?
Baking powder is typically used to make cakes rise. Baking powder is essentially, baking soda with an additional acid. When it reacts, it breaks down into carbon dioxide, water, and salt. The carbon dioxide causes bubbles in the cake mix, allowing the cake to rise.
