The terms "matter" and "non-matter" are used to categorize substances based on their physical properties and composition.
1. Matter: Matter refers to anything that occupies space and has mass. It is composed of atoms and molecules that interact with each other. Matter can exist in different states: solid, liquid, and gas. It can be further classified into pure substances and mixtures.
- Examples of matter:
- Iron: A solid metal that has a definite shape and volume.
- Water: A liquid substance that takes the shape of its container and has a definite volume.
- Oxygen gas: A gaseous form of oxygen that fills the space it occupies.
2. Non-matter: Non-matter, also known as "energy," refers to entities that do not occupy space and do not have mass. Non-matter is associated with the ability to do work, cause changes, or be transferred from one object to another.
- Examples of non-matter:
- Light: A form of electromagnetic radiation that travels in waves and can be perceived by the human eye.
- Heat: A form of energy that is transferred from a hotter object to a cooler one, causing a change in temperature.
- Sound: A form of energy produced by vibrations that can be detected by the human ear.
It's important to note that although energy is considered non-matter, it can interact with matter and cause changes in its properties or state. Both matter and non-matter play essential roles in the physical world and are interconnected in various processes.
