Are tarnishing and rusting physical or chemical changes?
Tarnishing is a chemical change as it involves a reaction with the metal's surface, often due to exposure to air or moisture. Rusting is also a chemical change, specifically the oxidation of iron in the presence of oxygen and water. Both processes result in the formation of new compounds on the surface of the material.
Is Making silver jewelry a chemical change?
No, making silver jewelry is not a chemical change. It involves physical processes like melting the silver, shaping it, and cooling it. The composition of silver remains the same throughout the process.
Is the luster of platinum jewelry physical or chemical property?
The luster of platinum jewelry is a physical property. Luster is a visual appearance attribute of the surface of a material, caused by the reflection of light. It is not a characteristic that involves a change in the chemical composition of the material.
Is the luster of platinum jewelry a physical change?
Yes, the luster of platinum jewelry is a physical change. The luster is a result of the surface properties of the platinum metal, such as its reflection of light, without any alteration to the chemical composition of the metal.
Is a Luster of gold jewelry is physical change?
Yes, the luster of gold jewelry is a physical change. It does not alter the chemical composition of the gold, but rather represents the way light interacts with the surface of the gold, giving it its shiny appearance.

Is tarnishing a physical change?
chemical, e.g. if you have silver, and it tarnishes, the dark spots (the tarnished areas) are actually silver oxide. If it were a physical change, the silver would need to change states of matter. Into gas, liquid or plasma

What is the weathering in which the chemical composition has changed?
It's called chemical weathering/chemical change. Similar to the physical change of matter, except the chemical composition changes causing it to become something completely different. For example: iron turns to rust, silver tarnishes and copper turns green.

Is tarnishing of costume jewelry physical of chemical change?
Tarnishing of costume jewelry is a chemical change. It occurs when the metal in the jewelry reacts with substances in the air, like oxygen or sulfur compounds, forming a new compound on the surface of the metal that gives it a dull or dark appearance.
