Classification of Matter

• • Substance
  • A form of matter that has definite composition and distinct properties.

   

  • This means that their composition will be the same no matter where you find them.
• • MIXTURE
  • A combination of two or more substances in which the substances retain their distinct identities.
• Mixtures are Either Homogenous and Heterogenous.
• HOMOGENEOUS

   

  • Homo is a prefix meaning one or uniform.
  • Geneousis a suffix meaning throughout.
• "Homogeneous" means uniform throughout or one throughout.
• • Homogeneous mixture it refers to a mixture whose composition is uniform all throughout.
  • There is an even or equal distribution of a substances that are combined together. 
• • The term "phase of matter" refers to a physically distinct and mechanically separable part of a system.

   
• Solutions

   

  • are Homogeneous mixtures of two or more substances whose particles are of atomic or molecular size
• A solution consist of two parts: Solute and Solvent
• SOLUTE - the substance being dissolved, which may be solid, liquid, or gas.
• SOLVENT - the substance doing the dissolving, which is usually a liquid.
• HETEROGENEOUS

   

  • Hetero is a prefix of two or more phases or unequal
  • Geneouses a suffix meaning throughout.
• • A heterogeneous mixture is one in which the different components are easily recognized
  • Two or more phases of matter can be seen.
• SUSPENSIONS

   

  • Are heterogeneous mixtures which contain large particles that tend to settle on standing.
• COLLOIDS

   

  • Are mixtures whose particles are larger than the ions or molecules in solutions.
• • A colloid has two parts,
  • The dispersing medium (Solvent) and;
  • The dispersed matter (solute)
• Colloids have very small particles compared with suspensions but they are too big to pass through a filter paper.
