- matter, material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. At the most fundamental level, matter is composed of elementary particles known as quarks and leptons (the class of elementary particles that includes electrons).

Jun 26, 2024 · The three most familiar forms, or states, of matter are solid, liquid, and gas. Heating and cooling a substance may change it from one state to another. When a material changes state, its smallest units, called molecules, behave differently.

Matter is a general term describing any 'physical substance'. By contrast, mass is not a substance but rather a quantitative property of matter and other substances or systems; various types of mass are defined within physics – including but not limited to rest mass, inertial mass, relativistic mass, mass–energy .
Jul 14, 2020 · In science, matter is defined as any substance that has mass and takes up space. Basically, it’s anything that can be touched. Yet, there are also phenomena that are not matter, such as light, sounds, and other forms of energy. A space devoid of all matter is called a vacuum.
The definition of Matter is anything that has mass and volume (takes up space). For most common objects that we deal with every day, it is fairly simple to demonstrate that they have mass and take up space.
- Solids. In solid state, the particles are tightly packed together which makes them incapable of moving freely. The forces or bonds holding the particles together are so strong that the particles only vibrate instead of moving.
- Liquids. In the liquid state of mater, the particles making up the substances are moderately loosely packed and incompressible. As a result, liquids have more kinetic energy compared to the solids.
- Gases. In the gaseous state of matter, the molecules have high kinetic energy which makes the intermolecular forces very small or close to zero. This makes the typical distance between the molecules is much greater than the molecular size.
- Plasma. Plasma is another state of matter that is quite common on earth. It is mostly widespread in the universe. Its composition is similar to a gas and as such, it lacks a definite shape or volume.
The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
