Science Separating Mixtures Year 7

Mixture of a soluble substance (Solute) being dissolved in solvent. Example sugar (soluble) and water (Solvent)

Evaporation (solvent evaporates)

A process separates the Solvent substances in a solution based on their boiling points. (the solvent is captured in a conical flask)

The temperature when a solvent substance evaporates. turns into a gas.

the temperature at which the vapor pressure of the solvent is the same as the external pressure.

A substance that is dissolved in a solvent

Can't be dissolved in a solvent

able to be dissolved in a solvent.

The liquid collected during distillation.

The soild form of a liquid.

When the solvent of a mixture is water.

a solution in which no more solute can dissolve

A mixture of a substance and a insoluble substance. Example sand and water.

Filtering, Decanting, Seiving and Separating funnel.

Matter that settles to the bottom of a liquid.

The substance that remains after separation

The measurement of how thick a substance or material is.

A mixture containing small, undissolved particles that do not settle out. Example is Paint

A colloid whitch is spread evenly through another.

something that you can controll in an experiment.

a variable that stands alone and isn't changed by the other variables you are trying to measure or find out.

is the effect that the indipent variable. example the sunlight is the indipent variable and the groth of the plant is the dependant as it is the effect of the sunlight.
