The formation of black crust on an object is a chemical change because it involves a chemical reaction between the surface of the object and the surrounding environment, resulting in the formation of a new substance with different properties.
The black crust is obtained by a chemical process; but the crust itself is a material not a change.

Is The starch in the pizza crust turns to sugar physical or chemical change?
The conversion of starch in the pizza crust to sugar is a chemical change. This process, known as hydrolysis, involves the breaking down of starch molecules into sugar molecules by reacting with water.
Is baking cookies a chemical change?
Baking a pie is a chemical change because the cells of the ingredients are broken down when they get hot. You can see this when the crust becomes firm or the fruit in a pie becomes soft.
Why are volcanoes a chemical change?
Volcanoes involve the release of gases, such as sulfur dioxide and carbon dioxide, through chemical reactions. These gases are produced as a result of the breakdown of rocks and minerals inside the Earth's crust, which represents a chemical change. Additionally, the formation of new minerals within volcanic rocks during the cooling process also represents a chemical change.
What kind of changesphysical or chemical if the starch in pizza crust turns to sugar?
The change from starch to sugar in pizza crust involves a chemical process called hydrolysis, where the starch molecules are broken down into simpler sugar molecules. This can occur during the baking process as heat and moisture trigger the breakdown of starch. The result is a sweeter taste in the crust due to the presence of sugars like maltose and glucose.
What does a mineralogist study?
A mineralogist studies minerals, which are naturally occurring inorganic substances with a specific chemical composition and crystalline structure. They investigate the physical and chemical properties of minerals, their formation processes, and their distribution in the Earth's crust. Mineralogists also play a crucial role in mineral exploration and resource management.
Is the starch in the pizza crust turns to sugar is the physical change?
Chemical
When silver coins are found in ancient shipwreck's they are coated with a black crust What question could you decide whether the silver underwent a chemical or physical change?
One question to determine if the silver underwent a chemical change would be to ask whether a new substance was formed during the formation of the black crust on the silver coins. If the black crust is the result of a chemical reaction between the silver and the elements in the shipwreck environment, then it indicates a chemical change took place.
Is baking a pie and chemical change or physical change?
It is both- the browning of the crust is a chemical change as well as any other browning. If the filling simply boils and loses moisture ,that is a physical change.
Is The starch in the pizza crust turns to sugar physical or chemical change?
The conversion of starch in the pizza crust to sugar is a chemical change. This process, known as hydrolysis, involves the breaking down of starch molecules into sugar molecules by reacting with water.
If graham crackers are crushed for a pie crust is that likely caused by a chemical reacion or chemical change?
Crushing the graham crackers is a physical change, not chemical. *Chemical reactions and chemical changes are the same thing.
Is rolling out a lump of pizza dough into a pizza crust is an example of a physical change?
no !
What slowly change earth crust?
Weathering, chemical change, and mechanical change. I hope i could help.
The outermost layer of the earth is called the?
The outermost chemical layer is the crust. The outermost physical layer is the lithosphere (the crust plus the attached uppermost mantle).
Is baking cookies a chemical change?
Baking a pie is a chemical change because the cells of the ingredients are broken down when they get hot. You can see this when the crust becomes firm or the fruit in a pie becomes soft.
What gets created by the physical process that change earth's surface by pushing its crust up or wearing it down?
Mountains are created by the physical process of pushing the Earth's crust up, while valleys and canyons are formed by the process of wearing down the crust through erosion.
What is an inorganic substance formed in earth with distinct chemical and physical properties?
A mineral is an inorganic substance formed in the Earth with distinct chemical and physical properties. Minerals have a specific chemical composition and a characteristic crystal structure. They can be found in rocks and are essential components of the Earth's crust.
What gets created by the physical processes that change Earths surface by pushing its crust up or wearing it down?
Water
