What happens to substances or materials that undergo physical and chemical changes?
That depends on which change.
Physical changes may result in a change in appearance, but never a change in composition. Ripping, folding, melting, boiling, dissolving, and crumpling are examples of physical changes. After all of these, the substance is still made of the same atoms/elements.
A chemical change will change both the appearance and composition of the matter. Examples of this are burning and reacting with acid. After the change, the substance both looks different and has a different makeup.

How you describe the changes that happened to the materials when heated?
When materials are heated, they can undergo physical or chemical changes. Physical changes include state changes like melting or boiling, while chemical changes involve the molecules rearranging to form new substances. Heating can also increase the kinetic energy of molecules, causing them to move faster and potentially break bonds.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes, physical changes involve a change in the appearance or form of a substance without forming new substances. Chemical changes, on the other hand, involve the formation of new substances through the rearrangement of atoms. Waste products may be formed in chemical changes as new substances are produced.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
How can materials be changed?
Materials can be changed through physical processes like cutting, crushing, or melting, as well as chemical processes like mixing with other substances, reactions with acids or bases, or heating to change their properties. These changes can result in different physical or chemical properties of the material.
What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
What are the good effects of physical change and chemical change?
Physical changes can include changes in size, shape, or state, while chemical changes involve the formation of new substances. Good effects of physical changes can include creating new materials like paper from wood pulp, while good effects of chemical changes include producing new medicines through chemical reactions. Both types of changes can be used to create new products and materials for various applications.

Heating can also increase the kinetic energy of molecules, causing them to move faster and potentially break bonds.
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes, physical changes involve a change in the appearance or form of a substance without forming new substances. Chemical changes, on the other hand, involve the formation of new substances through the rearrangement of atoms. Waste products may be formed in chemical changes as new substances are produced.
Is bread a chemical change?
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
What are facts about physical and chemical change?
Chemical changes take place on the molecular level
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Is ability to react with other substances chemical or physical?
The ability for a substance to react with other substances is a chemical property, as it involves changes in the substance's chemical composition. Physical properties, on the other hand, relate to characteristics such as color, shape, and state of matter, which do not involve changes in chemical composition.
How can materials be changed?
Materials can be changed through physical processes like cutting, crushing, or melting, as well as chemical processes like mixing with other substances, reactions with acids or bases, or heating to change their properties. These changes can result in different physical or chemical properties of the material.
