What Unique State of Matter Only Occurs at Extremely Low Temperatures: Solid, Liquid, Gas, Plasma, and Bose-Einstein Condensates
When we think of the different states of matter, we often consider the three main ones: solid, liquid, and gas. However, there are other states of matter that exist under specific conditions, and one of the most fascinating ones is the Bose-Einstein condensate (BEC). In this article, we will explore the different states of matter, including the unique state that occurs at extremely low temperatures.
Solid
A solid is a state of matter where the particles are closely packed and have a fixed position in space. The particles in a solid vibrate in place, but they do not change their position. Solids have a definite shape and volume, and they do not change shape when they are placed in a container. Examples of solids include rocks, metals, and ice.
Liquid
A liquid is a state of matter where the particles are close together but are free to move past each other. The particles in a liquid have some freedom of movement, but they are still attracted to each other. Liquids take the shape of their container and have a definite volume. Examples of liquids include water, oil, and juice.
Gas
A gas is a state of matter where the particles are widely spaced and are free to move in any direction. The particles in a gas have a lot of freedom of movement, and they are not attracted to each other. Gases have neither a definite shape nor a definite volume. Examples of gases include air, helium, and hydrogen.
What is Plasma?
Plasma is a state of matter that is created when a gas is heated to high temperatures, typically above 10,000 Kelvin (18,032°F). At these temperatures, the atoms or molecules in the gas are ionized, meaning that they lose their electrons and become charged particles. This creates a collection of charged particles, known as plasma, which can conduct electricity.
Properties of Plasma
Plasma has several unique properties that distinguish it from other states of matter. It is a good conductor of electricity, and it can be used to create high-energy beams and radiation. Plasma is also highly reactive, and it can be used to create a wide range of chemical compounds.
Examples of Plasma
Plasma is all around us, and it is created in a variety of ways. Some examples of plasma include:
- Lightning: During a lightning storm, the air is ionized, creating a plasma that can reach temperatures of up to 30,000 Kelvin (54,000°F).
- Stars: The sun and other stars are massive balls of plasma, where the energy released from nuclear reactions creates a hot, ionized gas.
- Plasma TVs: Plasma TVs use a layer of plasma to create images on the screen. The plasma is created by exciting a gas, such as neon or xenon, with an electric current.
What is a Bose-Einstein Condensate?
A Bose-Einstein condensate (BEC) is a state of matter that occurs at extremely low temperatures, typically below 170 nanokelvin (−273.15°C or −459.67°F). At these temperatures, a group of bosons, such as atoms or subatomic particles, can occupy the same quantum state, creating a single macroscopic wave function. This is known as a Bose-Einstein condensate.
Properties of Bose-Einstein Condensates
Bose-Einstein condensates have several unique properties that distinguish them from other states of matter. They are extremely cold, and they can be used to create highly sensitive instruments for measuring temperature and other physical properties. BECs are also highly coherent, meaning that they can be used to create highly stable and precise signals.
Examples of Bose-Einstein Condensates
Bose-Einstein condensates are created in a laboratory using a variety of techniques, including laser cooling and magnetic trapping. Some examples of BECs include:
- Rubidium BEC: In 1995, a team of scientists at the University of Colorado created the first BEC using rubidium atoms.
- Lithium BEC: In 1998, a team of scientists at the University of Colorado created a BEC using lithium atoms.
- BECs in space: In 2013, a team of scientists created a BEC in space using a satellite-based experiment.
In our previous article, we explored the different states of matter, including solid, liquid, gas, plasma, and Bose-Einstein condensates (BECs). In this article, we will answer some of the most frequently asked questions about these states of matter.
Q: What is the difference between a BEC and a superfluid?
A: A BEC and a superfluid are both states of matter that exhibit unusual behavior at extremely low temperatures. However, they are not the same thing. A BEC is a state of matter where a group of bosons occupy the same quantum state, creating a single macroscopic wave function. A superfluid, on the other hand, is a state of matter where a liquid exhibits zero viscosity and can flow without resistance.
Q: Can BECs be used for practical applications?
A: Yes, BECs have several potential practical applications. For example, they can be used to create highly sensitive instruments for measuring temperature and other physical properties. They can also be used to create highly stable and precise signals, which could be useful in fields such as telecommunications and navigation.
Q: How are BECs created?
A: BECs are created in a laboratory using a variety of techniques, including laser cooling and magnetic trapping. The process typically involves cooling a gas of atoms to extremely low temperatures, using a combination of lasers and magnetic fields to trap and cool the atoms.

Q: What is the relationship between BECs and superconductors?
A: BECs and superconductors are both states of matter that exhibit unusual behavior at extremely low temperatures. However, they are not the same thing. Superconductors are materials that exhibit zero electrical resistance at extremely low temperatures, while BECs are states of matter where a group of bosons occupy the same quantum state, creating a single macroscopic wave function.
