Everything in the world is made up of solids, liquids and gases. These are known as the three states of matter. They are all substances that have mass and take up space because they have volume. All those things around you are made of matter, so are you, as are the Earth and stars in the sky.

Matter is molecules that have combined together to create a substance. For instance H2O is the combination for water. Water is a liquid and it is one of the 3 main types of matter. The 3 main states of matter are liquid, solid, and gas. Matter has mass, anything that has mass is made of matter.

Matter is anything that has volume and weight.

Everything on earth has volume and weight. That means everything on earth is matter!
The amount of space something occupies is its volume. Solid items like tables, chairs and soccer balls, all take up space and therefore all have volume. Liquids like the water or milk you drink everyday or the water in a swimming pool also have volume. Even the air around us (which we cannot see but that we know is there) is made up of different gases and has volume.

What are the states of matter?

All materials fall into one of three categories: solids, liquids or gases. Each of these different groups has their own unique set of properties. Let us think about how we would categorize materials based on the following set of questions.

Can a material change shape? Solids are difficult to squash and therefore generally keep the same shape. Liquids and gases on the other hand change shape to fill the container they occupy.

Can a material flow? Solids don't flow but liquids and gases do.

Can a material change it's volume? Solids and liquids don't change much in volume. However it is easy to change the volume of a gas by squashing it.

Matter exists and can be categorized as a solid, a liquid or a gas. We call these three forms of matter - the states of matter. Of the many different substances that exist, most are found as solids at everyday room temperature. Far less exist as either liquids or gases.

How do solids, liquids and gases differ?

All materials whether they are solids, liquids or gases are made up of tiny particles of matter which are far too small to see with the human eye. The way in which these particles are arranged determines whether the material is a solid, a liquid or a gas.
What is a solid?
In a solid the particles are packed so closely together that they are hardly able to move at all. This is why solids have a definite shape and don't flow. Because the particles in a solid are packed so tightly a solid cannot be squished (compressed) easily into a smaller volume. It is not easy to compress, expand or change the shape of most solids because their particles are joined firmly to each other. A solid such as a pen cannot change into a completely different shape. There are some exceptions to this. For example materials like rubber can be easily stretched or bent without breaking even though rubber is a solid.
What is a liquid?
In a liquid the particles are also packed closely together but unlike solids the particles can move around each other. Particles in a liquid change places all the time. This is why liquids can flow very easily and because they have no definite shape of their own they always acquire the shape of the container in which they are held. A liquid will flow to the lowest point so it always fills the bottom part of a container first. Because their particles are packed closely together liquids, like solids, are difficult to squash (compress).
What is a gas?
A gas is mostly empty space. In a gas the particles are far apart and they move around easily. They spread out easily to fit any and all space available. Gases flow easily though this is more difficult to imagine because we usually cannot see a gas. Like liquids, because gases can flow they are also called fluids. It is easy to squish (compress) the particles of a gas more closely together so that is why it is easy to change the volume of a gas.

Can a material change from one state to another?

When we refer to a substance as a solid, liquid or a gas we are talking about it under normal, everyday conditions. Many substances though can exits in all three states of matter. The most common of these substances and the one most people are familiar with is water. Water can exist as a solid (ice), a liquid (water) and a gas (steam). A change of state occurs when a substance changes from one state to another for example when ice melts into water. When ice melts it changes from a solid state into a liquid state. A change in state is normally caused by changes in temperature (ice melts when its temperature rises) but a change in state can also be caused by changes in pressure.

Can matter be destroyed?

Matter cannot be created or destroyed - although it can change from one form to another. Scientists call this law the conservation of mass.

What is matter? Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).

What is mass? Mass is the amount of matter in an object. You might have a small object with a lot of mass such as a statue made of lead (Pb). You might have a large object with very little mass such as a balloon filled with helium (He). You should also know there is a difference between mass and weight. Mass is a measure of the matter in an object while weight is a measure of gravity's pull on an object.

What is volume? Volume is the amount of space something occupies. Words such as big, little, long, or short are used to describe volumes. A marble takes up a small volume while a star occupies a large volume. Different states of matter will fill volumes in different ways.

Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. We cover five states of matter on the site. Each of those states is sometimes called a phase. There are many other states of matter that exist in extreme environments. Scientists will probably discover more states of matter as we continue to explore the Universe.

What are the main states of matter? Everyone should know about solids, liquids, gases, and plasmas. Scientists have always known about solids, liquids, and gases. Plasma was a new idea when it was identified by William Crookes in 1879. We also like to talk about the Bose-Einstein condensate (BEC). It's a fun state of matter when you remove almost all energy from a system. The scientists (Cornell, Ketterle, and Wieman) who worked with the Bose-Einstein condensate received a Nobel Prize for their work in 2001.

What makes a state of matter? It's all about the physical state and energy in the atoms and molecules. Think about solids. Physical properties of a solid often include "hard" and "brittle." Liquids are fluidy, move around a little, and fill up containers. Gases are always around you, but the molecules of a gas are much farther apart than the molecules in a liquid. If a gas has an odor, you'll often be able to smell it before you can see it. The BEC is all about atoms that are closer and less energetic than atoms in a solid.

What is a physical change in matter? Molecules can move from one physical state to another ( phase change) and not change their atomic structure. Oxygen (O ₂) gas has the same chemical properties as liquid oxygen. The liquid state is colder and denser (less energy), but the molecules are the same. Water (H ₂O) is another example. A water molecule is made up of two hydrogen (H) atoms and one oxygen (O) atom. It has the same molecular structure whether it is a gas, liquid, or solid. Although its physical state may change because of different amounts of energy, its atomic structure remains the same.

So what is a chemical change in matter? Let's start with that glass of pure water. If the formula of water were to change, that would be a chemical change. If you could add a second oxygen atom to a water (H ₂O) molecule, you would have hydrogen peroxide (H ₂O ₂). The molecules would not be "water" anymore. In reality, there are a variety of steps that go into creating hydrogen peroxide from water.

Physical changes are related to changes in the immediate environment such as temperature, pressure, and other physical forces. Chemical changes occur when the bonds between atoms in a compound are created or destroyed. Generally, the basic chemical structure does not change when there is a physical change. Of course, in extreme environments such as the Sun, no molecule is safe from destruction.
