Verified step by step guidance

Understand the difference between physical and chemical processes. A physical process involves changes in the state or appearance of a substance without altering its chemical composition, while a chemical process involves a change in the chemical composition of substances.

Analyze each option: Freezing water is a physical process because it involves a change of state from liquid to solid without altering the chemical structure of water (H2O).

Consider tearing paper: This is a physical process as well, as it changes the shape and size of the paper but does not alter its chemical composition.

Examine rotating the bonds of a molecule: This is a physical process because it involves changing the spatial orientation of atoms within a molecule without changing the chemical bonds or composition.

Mixing acids and bases is a chemical process because it results in a chemical reaction that produces new substances, such as water and a salt, indicating a change in chemical composition.
