Phases of Matter

Plasma

Plasma is the most common form of matter in the universe, consisting of ionized gas with free electrons and ions.

Plasma Molecules

In plasma, molecules are ionized, meaning they have lost or gained electrons. This creates a mixture of positively charged ions and negatively charged electrons.

Properties of Plasma

• Variable Volume: Plasma expands to fill the volume of their container.
• Variable Shape: They conform to the shape of their container.
• Particle Movement: Molecules move freely and rapidly in all directions.
• Density: Generally less dense than liquids and solids.
• Compressibility: Plasma is easily compressed due to large spaces between molecules.
• Diffusion: Plasma molecules spread out and mix with other plasmas.
