Quiz Terms

Matter: anything that occupies space and has mass. Ex: all solids, liquids, and gases

Physical Properties: properties that can be observed and measured without changing the chemical makeup. Ex: density, freezing point of water

Density: the mass of material with a given volume. Ex: density of water is 1.00 g/mL

Freezing point: The temperature at which a liquid turns into a solid; it is the same volume as its melting point. Ex: the freezing point of water is 0°C at normal atmospheric pressure.

Aqueous Solution: a solution in which water is the solvent / water-based solution. Ex: distilled water.

Mixture : a combination of materials in which each material retains its separate identity. Ex: foul water

Heterogeneous Mixture: a mixture that is not uniform throughout. Ex:  coffee grounds settling to the bottom and were not distributed evenly in the foul water. Ex: Suspension

Suspension: a mixture containing large, dispersed solid particles that can settle out or be separated by filtration.  Ex: Water plus coffee grounds and water plus small pepper particles

Tyndall effect: the scattering of a beam of light caused by reflection from suspended particles. Ex: light shined through a sample of purified water

Colloid: a mixture containing solid particles small enough to remain suspended and not settle down. Ex: whole or low fat milk which contains small butterfat particles dispersed in water.

Homogeneous mixer: a mixture that is uniform throughout; a solution

Solution: a homogeneous mixture of two or more substances.

Solute: the dissolved substance. Ex: salt

Solvent: the dissolving agent. Ex water
