Solid |
Solids
Have a fixed shape and volume. Held closely together by strong forces of attraction called bonds. They vibrate to and from but cannot change position |
|
Liquids |
Liquids
Have a fixed volume, but not shape. The particles are close together and attract each other. They vibrate so vigorously that they can slide past each other. |
|
Gas |
Gases
Has no fixed shape or volume. Particles move freely, they are well spaced out. They move about at high speed, colliding with each other and walls of the container. |
|
Density |
Density = Mass / Volume
ρ = M / V |
|
Pressure |
Pressure = Force / Area
P = F / A |
|
Pressure Difference |
Pressure difference = Mass x density x height
P = m x ρ x h |
|
Brownian Motion |
The random movement of microscopic particles suspended in a liquid or
gas, caused by collisions with molecules of the surrounding medium.
