All changes in a phase are physical changes. These changes involve a rearrangement of the particles in the substance, but the actual particles themselves remain the same.
Examples of physical changes include melting of ice, boiling of water, cutting a piece of paper, breaking a glass, and dissolving salt in water. These changes alter the form or appearance of a substance without changing its chemical composition.
Scientists use a variety of methods, such as microscopy, spectroscopy, chromatography, and mass spectrometry, to identify physical changes in materials. These techniques help scientists observe changes in the size, shape, structure, composition, or properties of a substance, allowing them to understand how physical changes occur at a molecular level.
Physical properties describe characteristics of a substance that do not involve a change in its chemical composition, such as color or density. Physical changes, on the other hand, refer to alterations in the substance's physical state, like melting or boiling.
Changes of state are physical changes.
Yes. Chemical changes are changes in what things are made of, physical changes are changes of physical localization or state of matter ( liquid, solid, or gas)

Physical Changes
This is a physical change. Chemical changes are changes in "what things are made out of".

There are no physical changes. there are only chemical changes.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
As things grow and develop, they undergo physical changes such as increasing in size, gaining new features, and developing new functions. There may also be changes in behavior, skills, and capabilities as they mature. Additionally, there can be changes in relationships with other things and in their impact on their environment.

Physical changes in a substance result in
Fashioning a table leg from a piece of wood involves physical changes. The process of cutting and shaping the wood is a physical change as the composition of the wood itself remains the same, just the form and size are altered.
Changes in matter can lead to physical or chemical changes. Physical changes involve alterations in state or appearance, such as melting or crushing. Chemical changes involve the formation of new substances through reactions, like rusting or burning. Both types of changes can impact properties like color, texture, or composition.
