Which one of the following is NOT a physical process?

A. Dry ice subliming
B. Steam condensing
C. Alcohol evaporating
D. Melting ice
E. Gold plating jewelry

E-choice... Metallic plating is an electrolytic process based upon oxidation-reduction reactions and is a chemical process not physical process.

To determine which one of the given processes is NOT a physical process, we need to understand what physical processes are.

Physical processes involve changes in the physical properties of matter, such as changes in state (solid, liquid, gas) or changes in the physical appearance of substances, without any alteration in their chemical composition.

Let's analyze each option:

A. Dry ice subliming: Dry ice, which is solid carbon dioxide, directly changes from a solid state to a gaseous state without going through the liquid phase. This is a physical process.

B. Steam condensing: Steam, which is water in a gaseous state, changes back to its liquid state when it loses heat energy. This is a physical process.

C. Alcohol evaporating: Alcohol, as a liquid, changes to a gaseous state when it gains enough energy to overcome the intermolecular forces holding it together. This is a physical process.

D. Melting ice: Ice, which is water in a solid state, changes to a liquid state when heat is applied. This is a physical process.

E. Gold plating jewelry: Gold plating involves coating the surface of jewelry with a thin layer of gold using a process called electroplating. This process involves a chemical reaction between gold ions in a solution and metal ions on the surface of the jewelry. Therefore, gold plating is a chemical process, not a physical process.

Based on the above analysis, the option that is NOT a physical process is E. Gold plating jewelry.
