atoms
At very high pressure, solids can undergo phase transitions to form new crystal structures or even change into different phases of matter, such as becoming amorphous or liquid-like. The atoms or molecules in the solid are compressed together more closely, leading to changes in their arrangement and properties.
Physical properties can be tested without changing the substance a new substance. Color, density, volume and melting and/or boiling point are examples of physical properties that can be observed and/or tested.
When one or more new substances is created, the change is called a chemical change. A chemical change has occurred if there is a new substance created, there was energy released or absorbed, or the substances no longer exhibit the same chemical properties.
I think its a new substances is made so it changes the matter with it.
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.
Chemical change
Mixing different solids is a physical change because no new substance is formed and this mixture can be separated. it can be separated by using a method called magnetic separation
chemical change
Chemical Reactions
Energy is the ability to cause a change in matter.
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.

It is a chemical property. A chemical property is a characteristic of matter that allows it to change to a different type of matter.
All around us are substances that are made of matter. Matter has mass and occupies some space. Different kinds of substances are made up of different matter. Matter can be thus classified in many ways. Two basic classifications of matter are based on its physical and chemical properties. The physical classification of matter shows its physical appearance that describe the shape, hardness, softness, melting and boiling points. The chemical classification of matter shows the ability of matter to change its composition to form new substances. The different kinds of matter are gases, liquids, solids, and plasmas.
