Homogenous and Heterogenous
Homogenous is something that can't be separated from just looking at it a picking it away by hand, but heterogenous is something that you could pick away by hand. Homogeneous/ Brewed coffee/wine Heterogeneous/ Soil/sea water |
|
|
Viscosity
|
A liquids resistance to flowing.
