appearance - clear, transparent and homogeneous
particle size - molecule, in size, can not be filtered but can be separated by distillation
effect of light - none, light passes through, particles do not reflect light
effect of sedimentation - none

Suspension

appearance - cloudy, heterogeneous, at least two substances visible
particle size - larger than 10,000 angstroms, can be filtered and separated
effect of light - variable
effect of sedimentation - particles will eventually settle out

Colloid

appearance - cloudy but uniform and homogeneous, smoky foggy air
particle size - 10-1000 angstroms, will not separate
effect of light - light is dispersed by colloidal particles, visible light beam
effect of sedimentation - none
