Study Notes
Matter
- Matter refers to anything that has mass and takes up space.
- The kinetic particle theory states that matter is composed of particles in constant motion.
States of Matter
- Solid: Fixed shape, fixed volume, tightly packed particles, slow movement, strong forces of attraction between particles.
- Liquid: No fixed shape, fixed volume, particles have some space, medium movement, forces of attraction are less than solids but stronger than gases.
- Gas: No fixed shape or volume, particles are spread out, fast movement, very weak forces of attraction.
- Plasma: Consists of charged particles (ions and electrons) with high kinetic energy, exhibiting electrical conductivity and magnetic fields.
Plasma Examples
- Lightning
- Aurora
- Comet tail
- Solar wind
- Stars
- Interstellar gas clouds
- Welding arcs
- Interior of neon signs and fluorescent lights
- Interior of a plasma ball toy
- Static electricity
- Fireball of a nuclear explosion
- Earth's ionosphere
- Earth's magnetosphere
- Plasma displays of some televisions
- Rocket exhaust and thrusters
- Area in front of a heat shield during spacecraft re-entry
- Interstellar nebula
- Interstellar and intergalactic medium
- St. Elmo's fire
- Fire (if hot enough)
Bose-Einstein Condensate (BEC)
- A state of matter where atoms are cooled near absolute zero, resulting in the lowest possible quantum energy state for the atoms.
- Examples of BEC applications:
- Superfluid helium-4: Used in cryogenics and medical imaging.
- Superconducting materials: Used in MRI machines and particle accelerators.
- Lasers: Used in telecommunications and surgery.
- Atomic clocks: Used in navigation and telecommunications.
- Quantum information processing: Explored as a platform for storing and manipulating quantum information.
- Cosmology: Believed to have played a role in the early universe.
