Particles in motion Flashcards
Properties of a solid
Fixed volume
Fixed shape
Does not flow easily
Cannot be compressed
Properties of a liquid
Fixed volume
Takes the shape of its container
flows easily
Can be slightly compressed
Properties of a gas
No definite volume
No definite shape
Particles spread out/use maximum space
Can be compressed
Properties of solid particles
Particles close together
Arranged in a regular pattern
Particles vibrate around a fixed point
Properties of liquid particles
Particles close together
Particles arranged randomly
Particles slide over each other randomly and slowly
Properties of gas particles
Particles far apart
Arranged randomly
Move randomly and rapidly
Condensation
The change in state from a gas to a liquid
Evaporation
The change in state from a liquid to a gas below the boiling point of the liquid
Sublimation
The change in sate directly from solid to gas or gas to solidwithout the liquid state being formed
Brownian motion
The random movement of small visible particles in a suspension caused by the unequal random bombardment of molecules of liquid or gas on the visable particles
Diffusion
The spreading movement of one substance to another due to random motion of the particles
Kinetic theory
particles in solids, liquids and gases behave as hard spheres which are constantly mopving from place to place or vibrating
