It is the amount of substance that is able to
dissolve in a specific amount of a solvent, and
that is affected by temperature:

If water has high turbidity the temperature of the water increases.
TRUE
What are the characteristics of homogeneous mixtures?
We cannot see the different components.
The components cannot separate easily.
