How does the process of burning graphite affect its physical and chemical properties?
When graphite is burned, it undergoes a chemical reaction that changes its physical and chemical properties. The high temperature causes the graphite to oxidize, forming carbon dioxide gas and leaving behind ash. This process alters the structure of the graphite, making it more brittle and less conductive. Additionally, the burning of graphite can also lead to the formation of new compounds, such as carbon monoxide.

What process involves a change in physical properties boiling rusting fermenting burning?
The process described involves a chemical change. Boiling is a physical change as it involves a substance changing state from liquid to gas. Rusting, fermenting, and burning are chemical changes as they involve rearrangement of atoms in the substances leading to new chemical properties.
Is Mg burned in air chemical or physical?
Burning Mg in air is a chemical change. When magnesium reacts with oxygen in the air, it forms magnesium oxide. This is a chemical reaction that results in the formation of a new substance with different properties than the original magnesium.
Burning propane chemical or physical?
Burning propane is a chemical change because it involves a chemical reaction where the propane combines with oxygen to produce carbon dioxide and water vapor. This reaction results in the formation of new substances with different properties than the original propane.
Is the burning of methane gas in a cooker a physical or chemical change?
The burning of methane gas in a cooker is a chemical change. In this reaction, methane reacts with oxygen to produce carbon dioxide, water, and heat energy. This results in a new substance being formed with different chemical properties than the original methane gas.
Is burning chocolate a physical or chemical change?
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
Is burning a tortilla chemical or physical change?
Chemical; you are changing the physical properties of the tortilla. Physical would be just warming or cooling it for example
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
Is burning a chemical or physical properties?
Burning is a chemical process. The ability to burn, flammability, is a chemical property.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
Is burning a fire a physical or chemical change?
Burning is a chemical change.
Is burning salt a characteristic property?
No, burning salt is not a characteristic property. The physical and chemical properties of salt remain the same whether it is burned or not.
What process involves a change in physical properties boiling rusting fermenting burning?
The process described involves a chemical change. Boiling is a physical change as it involves a substance changing state from liquid to gas. Rusting, fermenting, and burning are chemical changes as they involve rearrangement of atoms in the substances leading to new chemical properties.
Is burning chemical change or physical change?
Burning is a chemical change.
Is burning fire physical or chemical change?
Burning is a chemical change.
Is burning of paper physical or chemical change?
Burning is a chemical process.
Is setting a piece of paper on fire a example of chemical change?
yes because it changes the physical properties of it as a paper by burning
