Answer 2

Answer:

- baking a cake, burning woods, cooking an egg

Explanation:

- When baking a cake the heat causes protein from the egg to change and make the cake firm. Burning woods are chemical changes, because When you burn wood, the carbon in the wood reacts with oxygen in the air to create ash and smoke, and energy in the form of light and heat. And lastly cooking an egg -  The heat from frying an egg causes the egg's protein to change permanently in texture and in appearance through a process called denaturing.
