The Study of Physical Science
This is the study of how atoms, molecules, and chemicals interact with each other.
Chemistry
The smallest unit into which an element can be divided and still maintain its properties.
Atom
A combination of substances that are not chemically combined.
Mixture
A mixture in which the particles of a substance are mixed throughout but large enough to settle.
Suspension
This is anything that has mass and takes up space.
Matter
This is the study of matter, energy, motion, and forces.
Physics
The use of paper or other materials to remove solid particles from a liquid mixture.
Filtration
A mixture in which the particles of a substance are dispersed throughout and are not large enough to settle.
Colloid
Chemistry and Physics
This is the unit of measurement used by all scientists.
Metric or International System of Units (SI)
A substance of constant composition that possesses definite qualities.
Pure Substance
A combination of substances in which the particles are not uniformly distributed.
Heterogeneous Mixture
Are colloids heterogeneous or homogeneous mixtures?
Heterogeneous
Homogeneous Mixture
If we are converting a unit of measurement into units which are larger, we do this.
Divide
A pure substance that cannot be broken down into simpler substances by physical or chemical means.
Element
A method of separating a liquid mixture by heating it so the liquid evaporates and condenses.
Distillation
This effect is caused by the scattering of light by colloids.
The Tyndall Effect
How can a colloid be distinguished from a homogeneous mixture?
The Tyndall Effect
If we are converting a unit of measurement into units which are smaller in size, we do this.
Multiply
A pure substance consisting of atoms of two or more elements that are chemically combined in a fixed proportion.
Compound
A method of separating mixtures according to how the different components are absorbed.
Chromatography
This is the only way you can separate a colloid.
In lab, we mixed sugar with water. The combination of sugar and water became a _______ mixture.
Homogeneous
