What Are the States of Matter?
Jan 11, · Example of a liquid state of matter: water, milk, blood, coffee, etc. Gas. In gases, particles are far apart from each other. Force of attraction between the particles is negligible, and they can move freely. Gases have neither a fixed volume nor a fixed shape. The gaseous state has the highest compressibility as compared to solids and liquids. The rate is diffusion is higher than solids and liquids. . Matter typically exists in one of three states: solid, liquid, or gas. The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids .
The three states of matter are solid, liquid and llquid. The particle model represents particles by small, solid spheres. It describes the arrangement, movement and energy of particles in a substance. The annd can be used to explain the physical properties of solids, liquids and gases.
The particles in the diagrams could be atomsmolecules or ions depending on the type of substance, eg ionic compoundssmall moleculesgiant moleculesand metals. A single particle does not have the properties of the material it is part of. The properties of a substance are the properties of a huge number of particles together.

Explaining properties A single particle does not have the properties of the material it is part of. Solids: have a fixed shape and cannot flow, because what are tax credits for particles cannot move from place to place liqjid be compressed squashedbecause their particles are close together and have no space to move into Liquids: flow and take the shape of their container, because their particles can move around each other cannot be compressed, because their particles zolid close together and have no space to move into Gases: flow and completely fill their container, because their particles can move quickly in all directions can be compressed, because their particles are far apart and have space to move into.
Solids, Liquids, Gases and Plasma
Apr 02, · States of matter are generally described on the basis of qualities that can be seen or felt. Matter that feels hard and maintains a fixed shape is called a solid; matter that feels wet and maintains its volume but not its shape is called a liquid. Matter that can change both shape and volume is called a gas.
Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter. Before we look at why things are called solids, liquids or gases, we need to know more about matter. Matter can be a confusing word because it has several meanings.
Scientists have a different meaning for matter — matter is anything that occupies space and has mass. Matter is made up of tiny particles. These can be atoms or groups of atoms called molecules. Atoms are like individual LEGO blocks. They are the smallest unit that anything can be broken down into without doing something extreme like hitting a LEGO block with a hammer or smashing atoms in the Large Hadron Collider. If atoms are like LEGO blocks, molecules are the structures you build with them.
The physical characteristics of atoms and molecules decide the form or state the matter is in. Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on a desk — all these things are solids.
Something is usually described as a solid if it can hold its own shape and is hard to compress squash. The particles in most solids are closely packed together. Even though the particles are locked into place and cannot move or slide past each other, they still vibrate a tiny bit. Ice is water in its solid form or state.
Ice keeps its shape when frozen, even if it is removed from its container. However, ice is different from most solids: its molecules are less densely packed than in liquid water. This is why ice floats. The simplest way to determine if something is a liquid is to ask this question: If I try and move it from one container to another i.
If you have a glass of water and pour it into another glass, it clearly conforms — it takes on the shape of the glass. If you spill the water, it will go everywhere. In most liquids, the particles are less densely packed, giving them the ability to move around and slide past each other.
While a liquid is easier to compress than a solid, it is still quite difficult — imagine trying to compress water in a confined container! Water is an example of a liquid, and so are milk, juice and lemonade. Find out more about water by looking at our wide range of resources under the water topic. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds.
A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
Think about a diving tank — L of gas is compressed into a 3 L cylinder. Right now, you are breathing in air — a mixture of gases containing many elements such as oxygen and nitrogen. Water vapour is the gaseous form or state of water. Unlike ice or water, water vapour is invisible. We exhale water vapour whenever we breathe out. We cannot see the water vapour as we exhale, but if we hold our eyeglasses or smartphone to our mouths, we can see the water vapour condensing becoming liquid on these objects.
One state is plasma, which naturally occurs in lightning, and we create it in fluorescent light bulbs and plasma TVs. Another state of matter is Bose-Einstein condensate, but this state only occurs with super-low temperatures. Science knowledge changes as we discover new evidence. Technology helps us find this evidence. To learn more about plasmas and Bose-Einstein condensates, read these two articles that look at these science ideas and concepts.
