States of Matter

Matter can exist in various forms, each with distinct physical properties and behaviors. The four primary states of matter are solid, liquid, gas, and plasma, while other states such as Bose-Einstein condensates and Fermionic condensates are created under extreme conditions in a laboratory.

Solid

In a solid, particles (ions, atoms, or molecules) are closely packed together. The forces between particles are strong, preventing the particles from moving freely and allowing the solid to maintain a fixed volume and shape. Solids are characterized by their stable, definite shape and volume, and they can only change shape by an outside force such as cutting or breaking. In crystalline solids, particles (atoms, molecules, or ions) are packed in a regularly ordered, repeating pattern, and the same substance can have more than one structure (or solid phase) depending on the temperature and pressure conditions.

Liquid

In a liquid, particles are more loosely packed than in a solid and are able to flow around each other. This gives the liquid an indefinite shape, allowing it to conform to the shape of its container. While liquids have a fixed volume (assuming no change in temperature or air pressure), they are incredibly difficult to compress due to the repulsive forces between their particles.

Gas

In a gas, particles have a great deal of space between them and have high kinetic energy, leading to their ability to move freely. A gas has no definite shape or volume and will expand to fill its container if unconfined. When a gas is put under pressure by reducing the volume of the container, the space between particles is reduced, causing the gas to compress.

Plasma

Plasma is the most common form of visible matter in the universe and is not a common state of matter on Earth. It consists of highly charged particles with extremely high kinetic energy. The noble gases, such as helium, neon, argon, krypton, xenon, and radon, are often used to make glowing signs by ionizing them to the plasma state. Stars like the sun are essentially superheated balls of plasma.

Other Exotic States

Bose-Einstein condensates (BECs) are created by cooling a sample of atoms to within a few degrees of absolute zero. At these extremely low temperatures, molecular motion comes very close to stopping, and the atoms begin to clump together, forming a "super atom" with many of the properties of a superfluid. Other exotic states of matter include fermionic condensates, which are created under extreme cold conditions, and quark-gluon plasma, which is believed to exist at extremely high energy levels.
