That green stuff that shows up on copper is called verdigris, and is also known as patina. In addition to making your penny green, it's also what makes the copper Statue of Liberty look green!
The process by which verdigris is made is called oxidation. Most of the time, when copper oxidizes, it turns dark brown, like most pennies you see. When saltwater is added (like in somebody's sweaty pocket) the copper turns green instead.
The process is called oxidation. When a penny is exposed to air and moisture, the copper in the coin reacts with oxygen to form copper oxide, which gives the penny its green color.
A copper penny turns green due to oxidation.
When oxygen combines with copper, it produces copper oxide, which is green, in color.
Vinegar, after being combined with salt.
The process of turning a liquid back into ice is called freezing.
The name "Foamposite" comes from the material used in the construction of the shoe, which is a polyurethane foam with a liquid injection molding process. This technology was originally developed for military footwear before being adapted for Nike's basketball shoes.
The substance that gives green structures their color is chlorophyll. Chlorophyll is a pigment found in plants that plays a key role in photosynthesis, the process by which plants convert sunlight into energy.
The chemical element chlorine gets its name from the Greek word "chloros," which means "pale green" or "yellow-green." Chlorine gas has a yellow-green color, which inspired its name.
Sublimation is the process in which a solid turns directly into a gas without passing through the liquid state.
hello
The process is evaporation.
yes her name is taylah green.

freezing
The name of the process is 'Melting'. It is that because the solid is melting into a liquid.

When a gas turns into a liquid this is known as condensation.
The process of a liquid becoming a gas is "evaporation". The liquid 'evaporates' to become a gas.
