The substance of the physical world is commonly referred to as "matter." Matter comprises anything that has mass and occupies space, including solids, liquids, gases, and plasma. It is made up of atoms and molecules, which interact through various physical and chemical processes. In a broader philosophical context, some may also refer to the essence of the physical world as "materialism" or "physicalism."
physical change
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
Chemical and physical properties
A pure substance.
When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
Physical change
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
It's called a physical change.
A physical change does not change the substance.
It's called a physical change.
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.

physical change
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.
