Matter is the “stuff” that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons, and electrons. There are basic states of matter: Solid, Liquid, Gas, and Plasma.

Key Facts & Information
- Matter makes up everything including living things such as plants, animals, and people.
- It also makes up nonliving things such as paper and pens.
- One characteristic of matter is that it occupies space. Water can fill up a jar, air fills up an empty balloon, and soil fills up a clay pot.
- Matter also has mass. Mass is the amount of matter that an object has.
- This means that some objects have more mass in them. Some have less.
- Matter has weight. It is the gravitational force acting on a body of mass directed towards the center of the earth.
- Matter also has properties. Physical property is any property that can be observed by using simple tests and measurements without changing the identity of the matter.
- Expensive property depends on the amount of the material.
- Intensive property depends on the quality of the material.
SOLID STATE OF MATTER
- Solid is the state of matter that has a definite shape. It can be described and identified by their physical properties: color, texture, hardness and odor.
- The molecules of a solid are tightly held together by the forces of attraction between them. They are compact and compressed, so they cannot move freely.
- This keeps the shape of the solid material. Solids have rigid shapes.
- A coin is also solid. It is in the shape of a circle. You cannot change its shape unless you break it.
- Rose and gumamela are flowers. The former has smell while the other does not.
- Apples and glasses are solids. One tastes sweet and the other does not have taste nor color.
LIQUID STATE OF MATTER
- Liquids consist of particles that are close together with no set arrangement, can flow easily, can take on the shape of any container it occupies, and cannot be compressed easily.
- The molecules of liquids are free to move and have spaces between them. Due to this, liquid cannot set a specific shape of its own.
- Liquid can occupy space by filling up the spaces between the molecules of a solid matter.
- The flow of liquid depends on its viscosity. Viscosity is the resistance of liquid to flow. Milk flows slower than water because milk is more viscous than water.
- Liquid molecules have less cohesive attraction than solids and more than gases, which is why a liquid is not quite solid, yet still firmer than gas.
- Liquids also change form when exposed to extreme temperatures.
- They can boil, evaporate, freeze, condense, and form solutions.
GASEOUS STATE OF MATTER
- One of the most distinguishing characteristics of a gas is that it has no definite volume or shape.
- However, it still occupies space but generally has no odor or taste.
- When gases are mixed with other chemicals, they produce color and smell. Smoke from factories is visible and smelly but we cannot touch it.
- Gas molecules also do not slow down or stick to other gas molecules or to objects. It moves constantly.
- For example, the gas leaving the fire on a torch will move up and away from the fire.
- In short, if unconfined, the particles of a gas will spread out indefinitely; if confined, the gas will expand to fill its container.
- Gas becomes vapor when its temperature is below its critical temperature, and can be liquefied by compression alone without cooling.
- A liquid may be converted to a gas by heating at constant pressure to the boiling point, or by reducing the pressure at constant temperature.
PLASMA STATE OF MATTER
- Plasma is defined as a state of matter composed of ions and electrons.
- It is not a common state of matter on our planet, but it may be the most common state in the universe.
- Plasmas are basically formed by heating gas to scorching temperatures.
- When heated, the atoms in the gas may gain or lose electrons (ionization). The end result is a charged particle plasma.
- Plasma is commonly generated by either lightning, electric sparks, fluorescent lights, neon lights, or in plasma televisions.
- Plasmas are also widely researched by many scientific studies, in particular fusion reactors.
- In this process, high energy plasmas are created in order to fuse Hydrogen atoms to make Helium, making it similar to the production of powers on stars in the universe.
