Pouring tang into water is a chemical change. A change a said to be chemical if it changes color, taste, volume etc. Pouring tang into water causes a chemical change because the color changes and the volume of the tang changes because it is in a liquid state.
Making oatmeal involves both physical and chemical changes. The physical change occurs when oats absorb water and swell, altering their texture. A chemical change can also happen as the heat causes starches in the oats to gelatinize, changing their chemical structure and flavor. Overall, the process predominantly features physical changes, but the cooking aspect introduces some chemical changes as well.
No it's not because all you are doing is melting the gold, putting in into a mold and letting it harden. It would be a chemical change if you added some other substance to it during the progress.

No, mixing brown sugar into oatmeal is a physical change, not a chemical change. The brown sugar and oatmeal retain their original properties and can be separated back into their individual components. Chemical changes involve a rearrangement of atoms and the formation of new substances.
Pouring molten gold in a mold is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the gold.
Pouring tang into water is a chemical change. A change a said to be chemical if it changes color, taste, volume etc. Pouring tang into water causes a chemical change because the color changes and the volume of the tang changes because it is in a liquid state.
