8Th Grade; Physical Science

Front 1

What is a Universal Solvent

Back 1

Water

Front 2

How would you speed up the dissolving process of a frozen good?

Back 2

You could stir it, heat it

Front 3

A heterogeneous is what?

Back 3

This type of mixture does not have a fixed composition. The amount of each substance in different samples of a heterogenous mixture varies, just as the amount of fruit varies in a spoonfull of fruit salad.

Front 4

A homogeneous mixture is what?

Back 4

Looks uniform even when you examine it under a microscope because the individual components of the mixture are to small to be seen.

Front 5

Suspension

Back 5

a mixture in which particles of a material are more of less evenly dispersed throughout a liquid or gas and settle out, such as a snow globe.

Front 6

Colloid

Back 6

a mixture consisting of tiny particles that are intermediate in size and do not settle out, such as milk

Front 7

Solutions

Back 7

A homogeneous mixture throughout which two or more substances are uniformly dispersed

Front 8

Solute

Back 8

In a solution, the substance that dissolves in the solvent (Mrs. Owens' packet of awesomeness)

Front 9

Solvent

Back 9

In a solution, the substance in which the solute dissolves
ex: water

Front 10

Alloy

Back 10

a solid or a liquid mixture of two or more metals
ex: brass, bronze, air

Front 11

Solubility

Back 11

The solubility of a substance is the maximum mass of a solute that can dissolve in 100g of solvent at a certain temperature and standard atmospheric pressure

Front 12

Concentration

Back 12

the amount of a particular substance in a given quantity of a mixture or solution

Front 13

Saturated Solutions

Back 13

A solution that cannot dissolve any more solute under the given conditions

Front 14

Unsaturated Solutions

Back 14

A solution that contains less solute than a saturated solution does and that is able to dissolve additional solute

Front 15

Supersaturated Solution

Back 15

A solution that holds more dissolved solute than is required to reach equilibrium at a given temperature

Front 16

A solution is _______________ as long as more solute can dissolve in it

Back 16

unsaturated

Front 17

Supersaturated Solution

Back 17

A solution that holds more solute than it normally would at a cooler temperature
