Physical changes are changes that do not alter the chemical composition of a substance, such as changes in state (solid, liquid, gas) or shape. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.

What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Changes in properties of matter are called?
physical or chemical changes.
How is physical. change different than a chemical. change?
physical changes can be not permanent like solid-liquid-vapour chemical changes are permanent if not reversible
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Contrast physical changes with chemical changes?
i have no idea im the one thats asking you s*n of a bi*c*
What is always involved when physical or chemical changes occur in matter?

Are all physical changes accompanied by a chemical change?
No, physical changes involve a change in appearance, texture, or state of matter without altering the chemical composition of the substance. In contrast, chemical changes result in the formation of new substances with different chemical properties.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Changes in properties of matter are called?
physical or chemical changes.
Which is easier to reverse chemical or a physical change?
Physical changes are generally easier to reverse than chemical changes. Physical changes involve a change in state or appearance without altering the chemical composition of a substance, so reversing the change often involves a simple process like melting, freezing, or evaporating. In contrast, chemical changes involve the formation of entirely new substances with different chemical properties, making them more challenging to reverse.
Are state changes chemical or physical changes?
Physical Changes
How is physical. change different than a chemical. change?
physical changes can be not permanent like solid-liquid-vapour chemical changes are permanent if not reversible
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
