physical change
Physical.
A physical change is a change in a substance that does not involve a change in the substance's chemical identity. Instead, physical changes only affect the state, shape, or size of the material without altering its composition. This can include changes such as melting, freezing, boiling, or dissolving.
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
A physical change is a change in the appearance, texture, or shape of a substance without changing its chemical composition. Examples include melting an ice cube, tearing a piece of paper, or boiling water. These changes are usually reversible and do not result in the formation of a new substance.
A chemical change in matter produces a new substance. A physical change, on the other hand, only alters the state or phase of matter without producing a new substance.
physical change
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.

that is called a physical change.
During a physical change, the composition of matter remains the same. The atoms and molecules of the substance do not change; only the arrangement or state of the matter is altered. This means that no new substances are formed during a physical change.
During a physical change, the matter retains its chemical composition but its physical properties (such as shape, size, or state) may change. On the other hand, during a chemical change, the matter undergoes a chemical reaction, resulting in the formation of new substances with different chemical compositions.
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
