Chemical reaction
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.

Energy is the ability to cause a change in matter.
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.
a chemical change
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.

Nuclear and Chemical changes result in new substances.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
chemical reaction. In a chemical reaction, the atoms of one or more substances are rearranged to form new substances with different properties. This process involves breaking and forming chemical bonds.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.

By heating or freezing.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.
