Study Notes
What is Matter?
- Matter is anything that has mass and occupies space.
- It is composed of atoms and can exist in various physical states.
What is Not Considered Matter?
- Energy, such as light and heat, is not considered matter.
- Concepts like thoughts, emotions, and ideas do not possess mass or volume.
Different States of Matter
- Solid: Defined shape and volume; particles packed tightly together.
- Liquid: Defined volume but no fixed shape; particles are close but can move past each other.
- Gas: No fixed shape or volume; particles are far apart and move freely.
Difference Between Atoms and Particles
- Atoms are the fundamental building blocks of matter, consisting of protons, neutrons, and electrons.
- Particles can refer to atoms or smaller components (like molecules, ions, or subatomic particles); thus, all atoms are particles, but not all particles are atoms.
Phases of Matter Beyond Solid, Liquid, and Gas
- Plasma: Ionized gas with free-moving ions and electrons; found in stars and lightning.
- Bose-Einstein Condensate: State of matter formed at near absolute zero, where particles occupy the same quantum state.
- Fermionic Condensate: Similar to Bose-Einstein condensate but formed with fermions paired at extremely low temperatures.
Why Photons Are Not Considered Matter
- Photons are massless particles of light; they do not have rest mass and do not occupy space.
- Despite carrying energy and momentum, their lack of mass disqualifies them from being categorized as matter.
