How can we classify solutions based on the solvent? (Not the definition)
Aqueous, Non-aqueous
What is used for the process of filtration
Filter paper
Temperature makes a solid dissolve faster. How does this happen?
The particles in matter are always moving. When we increase the temperature the heat adds energy and makes the particles move faster.
How can we make a solid dissolve faster?
Stirring, temperature and size
What mixtures does filtration separate?
Heterogeneous mixtures
Evaporation is used to separate what mixtures?
Heterogeneous and homogeneous
What are the parts of the solotion?
Solute, solvent
How are solutes classified based on the amount of solute? (Not the definitions)

Stirring makes a solid dissolve faster. How?
Stirring causes the particles of the solute to spread out into the spaces of the solvent more quickly.
What is a substance?
