Chemical changes very often happen when you prepare a meal. For example, when cooking a cake, the yeast reacts and the cake rises. Whenever something changes and you cannot reverse that change, it is a chemical change whereas if you can change it back, it is a physical change!
Food energy is used for heat and motive energy (muscle contraction).
food these days are made with chemicals anyways.
Cooking food (including frying it) does produce chemical changes.
This darkening involve chemical reactions.
Yes

The food Darkens
This darkening involve chemical reactions.
Chemistry plays a critical role in the kitchen by influencing the physical and chemical changes that occur during cooking and food preparation. For example, the Maillard reaction is a chemical reaction that occurs when cooking food at high temperatures, leading to the browning of food and development of complex flavors. Understanding these chemical processes can help in improving food texture, flavor, and overall cooking techniques.
Both of those processes are parts of cooking. It depends on what you're doing. If you're melting or freezing its a physical change. If you're changing it into another substance then its chemical. A chemical change is when a substance is changed into another entirely different substance. This happens when an event occurs that changes the composition of the substance. Examples of chemical changes are color changes, absorbing energy, releasing energy, odor changes, producing gases, producing solids, and can't be easily reversed. A physical change is when there is a change is physical properties. This happens when an event occurs that doesn't change their chemical. Examples of physical changes are changes in the texture, shape, size, color, odor, volume, mass, weight, and density.
