What is a solute?
the substance that dissolves IN the solution (eg sugar)
What is a mixture?
When two or more substances mix with each other without participating in a chemical change, the resulting substance is called a Mixture
What is a heterogeneous mixture?
A mixture that has different or non-uniform composition
What is the residue of a mixture?
The solid left behind in the filter paper when filtering
When a solid is capable of dissolving in a liquid it is...
Soluble
What is magnetism?
A way to separate components in a mixture that displays magnetic and non-magnetic properties.
What is evaporation?
Evaporation uses heat to separate a soluble solid from a liquid
What is the filtrate?
The liquid that passes through the filter paper when filtering
What is filtering?
Separating a solid from a liquid when they don’t dissolve. The liquid passes through filter paper to do this
What is a solution?
what is created when a substance dissolves in a solvent
TRUE OR FALSE: When matter is in a solid state, it has very little energy and molecules stay together
TRUE
TRUE OR FALSE: When matter is in a gase4ous state, it has less energy and the molecules are together
FALSE
What is a homogeneous mixture?
A mixture that has same or uniform composition
What is a solvent?
the substance that does the dissolving in the solution (eg water)
What do we use condensation for during distillation?
The liquid component that boils at a lower temperature evaporates first, and as a gas, passes through a cooling chamber where it condenses.

What is distillation?
Separating a liquid from a solution by evaporating the liquid and then condensing it.
When a solid is not capable of dissolving in a liquid it is...
