A physical change occurs.
The chemical that can change rock into a brownish color is often iron oxide, also known as rust. This process occurs when the iron in the rock reacts with oxygen to form iron oxide, giving the rock a brownish appearance.
When you create a mixture and a change occurs, it is called a physical change. This means the substance's state or appearance has altered, but its chemical composition remains the same.
Boiling causes water to change from its liquid state to a gaseous state, known as steam or water vapor. This transformation occurs when the water reaches its boiling point, typically 100°C (212°F) at sea level, where the molecules gain enough energy to break free from the liquid's surface. As a result, boiling is a physical change that alters the state of matter from liquid to gas.
A change in the composition of matter occurs during every chemical reaction. This involves the breaking and forming of chemical bonds, leading to the rearrangement of atoms to create new substances with different properties.
Tarnishing of a silver spoon is a chemical change. It occurs when the silver reacts with sulfur compounds in the air or food, forming silver sulfide. This chemical reaction alters the composition of the spoon, resulting in the tarnished appearance.
no physical change does not change matter
The physical change that occurs when a gold coin is stamped with an eagle is the impression or design of the eagle being embossed or impressed onto the surface of the coin. This process alters the appearance of the coin by adding the eagle image to it.

Yes, a physical change occurs when matter changes state. This change is reversible and does not alter the chemical composition of the substance. Examples include melting, freezing, vaporization, and condensation.
It is a physical change.
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
