Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. 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.
Does a phsical change or chemical change affect the matter in an object?
Both physical and chemical changes affect the matter in an object. Physical changes alter the object's state or appearance without changing its chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
What are physical changes in biology?
Physical changes in biology refer to changes that affect an organism's physical appearance but not its chemical composition. Examples include changes in size, shape, color, and texture. These changes are reversible and do not involve any alteration in the organism's DNA.
What is the difference between chemical and physical changes?
Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties. Physical changes, on the other hand, only affect the physical state of a substance (such as its shape, size, or phase) without changing its chemical composition.
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.
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.

Which is a example of a physical rather then a chemical change?
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
When gold changes from a solid to a liquid is that a physical or chemical change?
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
Are changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
Does a phsical change or chemical change affect the matter in an object?

What is one major difference in a physical change and a chemical change is?
One major difference between a physical change and a chemical change is in the composition of the substance. In a physical change, the substance retains its chemical composition and only its physical appearance is altered, while in a chemical change, new substances with different chemical compositions are formed.

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
