Neither. Hash Brown refers to a style of cooking potatoes in which the potatoes are shredded raw, flattened into about a 1/2" thickness and then browned on both sides by pan frying either on a griddle or in a frying pan using a small amount of fat.
When the potatoes are first peeled and sliced however, they can start to turn brown if exposed to oxygen and not cooked due to enzymatic browning (a chemical reaction). When the hash browns are fried, the exterior will turn brown through a chemical process known as the "Maillard Reaction."
A metal Surface being ground is a physical change, not a chemical change.
Physical. The properties of the metal do not change, and it can be undented.
It is a physical change because you are changing the shape of the metal.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
Tarnishing of metal is a chemical change because it involves a reaction between the metal and substances in the environment (such as oxygen or sulfur compounds) that forms a new compound on the surface of the metal, altering its properties.
Physical change
Corrosion is a chemical change
No, it is a chemical change. The metal oxide formed is a new substance.
chemical change
Vaporization is a physical change.
A metal Surface being ground is a physical change, not a chemical change.
Physical Change, the metal has the same chemical structure and only the shape of the bar has changed
Physical. The properties of the metal do not change, and it can be undented.
It is a physical change because you are changing the shape of the metal.
Metal rusting (corrosion) is a chemical change.
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
It is a physical change because only its shape changed, not its chemical composition.
