There is a machine that changes dirty water to clean water
There are two levels of clean when talking about sterling silver jewelry. The piece of sterling jewelry could be either simply dirty or tarnished or both. If the piece is only dirty a solution of Mr. Clean, water, and ammonia can be used. Mix half water and Mr. Clean with a small amount of ammonia. This is the same solution many jewelers I know use in their ultrasonic to clean all types of fine jewelry. Allow the jewelry to soak for 15 seconds then rinse with water and dry. You can repeat if need be. More likely than not sterling jewelry is also tarnished. Sterling does tarnish much quicker than gold or platinum. Removing tarnish from sterling silver jewelry is easy. Mix just enough water with baking soda to make a paste and use the paste to rub on the jewelry to remove the tarnish. Rinse with water then dry.
It is a Physical Change because i dont know but im sure that is a physical change :P
Evaporation of a pudle is a physical change,
When water vapor condenses into liquid water droplets in a cloud during a thunderstorm, it releases energy in the form of latent heat. This process of condensation is exothermic, meaning it releases heat into the surrounding environment.
A change in matter that does not change the individual molecules is a physical change. During a physical change, the substance retains its molecular structure but undergoes a change in properties such as shape, size, or state (solid, liquid, gas). Examples include melting, freezing, dissolving, and phase changes.
