Matter Basics Quiz

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.
