Photosynthesis involves a chemical change.
Moving furniture is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, while a physical change involves a change in the physical state or appearance of a substance without altering its chemical composition. When you move furniture, you are simply changing its position or location, which is a physical change.
Fermenting cheese is considered a chemical change because it involves the breakdown of proteins and fats by the action of bacteria, enzymes, or other microorganisms, leading to the formation of new compounds and flavors. This results in the transformation of the cheese at a molecular level, which is why it is classified as a chemical change rather than a physical change.

Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Burning wood is an example of an action that involves a chemical change. During the burning process, the wood undergoes a chemical reaction with oxygen in the air, resulting in the production of heat, light, and new substances such as carbon dioxide and ash.

Charring of sugar is a chemical change because it involves the chemical decomposition of the sugar molecules due to the application of heat, leading to the formation of new substances like carbon. This change is irreversible and involves the breaking and rearranging of chemical bonds.
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
chemical
A phase change is a physical change that involves rearranging the molecules in a substance without changing its chemical composition. In contrast, a chemical reaction involves the breaking and forming of chemical bonds, resulting in the formation of new substances with different chemical compositions.
