Classifications Of Matter Flashcards
What is a chemical change
Any change that results in the formation of new chemical substances. It involves the making or breaking of bonds between Adams
What is a colloid
A homogeneous substance consisting of large molecules or ultra microscopic particles of one substance disbursed through a second substance. They include gels and emotions. Particles cannot settle and cannot be separated out by ordinary filtering like those in a suspension
What is a combustion
A reaction in which one of the reactance is oxygen reacting with something else
What is a composition
Refers to the arrangement, type, and ratio of Adams in molecules of chemical substances
What is a compound
Is a substance formed when two or more chemical elements are chemically bonded together the two types of chemical bonds common compounds are covalent bonds and ionic bonds
What is conductivity
Degree to which a specified material conduct electricity
What is conservation of mass
Principal stating that mass cannot be created or destroyed
What is density
It is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up volume. The mass of Adams, their size and how they are arranged term is the density of a substance
What is distillation
The process of separating the component substance from a liquid mixture by selective evaporation and condensation
What is malleable
The ability of a substance, usually a metal, to be deformed or molded into a different shape
What is a mixture
It is a material System made up of two or more different substances which are mixed but not chemically bonded it refers to the physical combination of two or more substances of which the identities are retained and are mixed in the form of solutions suspensions and colloids
What is the physical
Physical changes are changes affecting the form of a chemical substance but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but not usually be used to separate compounds into chemical elements or simpler compounds
What is pure substance
Substances that are made up of only one type of Adam or molecule the purity of a substance is the measure of the extent to which a given substance is pure
What is a suspension
A suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation
What is the Tyndall effect
A light scattering by particles in the colloid or particles in a fine suspension
What is uniform
It is like a pure substance
What is an alloy
A metal made by combining two or more metallic elements especially to give greater strength or resistance to corrosion
