Making tea using hot water and a tea bag is primarily a physical change. The process involves the extraction of flavors, colors, and compounds from the tea leaves into the water, but the chemical composition of the tea itself remains largely unchanged. While some minor chemical interactions may occur, such as the release of antioxidants, the overall process is characterized by a physical mixing rather than a chemical transformation.

No, this is definitely a physical change, absolutely not a chemical.
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
No. It is a physical change.

Boiling water is a physical change because it does not change the chemical composition of the water.
Ocean water is a substance, not a physical or chemical change.

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.

Condensation of water is a physical change.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
No, this is definitely a physical change, absolutely not a chemical.
