-
Arrangement of particles
- Solid: Tightly packed, even rows and columns
- Liquid: Loosely arranged, flowing over each other
- Gas: Widely spaced, some collisions
-
Motion of particles
- Solid: Vibrate in fixed position
- Liquid: Move past each other and vibrate
- Gas: Random movement (straight lines), some collisions
-
Forces between particles
- Solid: Very strong bonds
- Liquid: Some weak bonds
- Gas: No bonds except during collision
-
Absolute zero
- Matter cannot be cooled more
- As less energy as element gets
-
Evaporation
Particles at top of liquid have more energy to become gas
- Larger surface area
- More moving air on surface (wind)
- Greater exposed surface area
-
Pressure-volume graphs
-
- As volume increases, pressure decreases
- 1/volume provides a linear graph through the origin with pressure.
