An example of a cloudy mixture would be
a solution
a colloid
a solute
a solvent
If something is dilute, it means that
there is a small amount of solute compared to the solvent in a solution
there is a lot of solute compared to the solvent in a solution
there the same amount of solute and solvent in a solution
there is no solute in a solution
The opposite of dilute is (a)
The mixing of a solid with a liquid to form a solution is called
suspension
colloid
emulsion
dissolving
When salt is mixed with water so that the salt disappears, the salt is the (a) in the solution
A change of state from liquid to a gas is called
evaporation
condensation
melting
freezing
Evaporating the solvent from a solution increases the (a) of the solute
