![]() The ChemEd site at Purdue University features a number of descriptive pages on properties of matter including the article entitled “ Melting point, Freezing Point, Boiling Point,” which compares these three related properties. Density is explained both physically and mathematically with several examples in the Virtual Chembook from Elmhurst College. Electrical conductivity is a measure of the ability of a material or object to conduct electricity.ĭensity.Thermal conductivity is a measure of the ability of a material or object to conduct heat. ![]() Solubility is the property of a solute (solid, liquid, or gas) to dissolve in a solvent (solid, liquid, or gas) to form a homogeneous solution (e.g., mixture) or solid.The boiling point of an element or substance is the temperature at which the vapor pressure of the liquid equals the external pressure surrounding the liquid.Density of gases and liquids vary with temperature. The density of matter of an object is its mass per unit volume.Matter consists of atoms and other particles that have mass. Matter is anything that occupies space and possesses mass.density, boiling point, solubility, thermal and electrical conductivity). The beginning teacher describes the physical properties of substances (e.g. Applications to Processes and Situations in Life and Earth/Space Science.Physical and Chemical Changes in Matter.Physical Properties of Elements and Placements in the Periodic Table.Relationship between Molecular Structure and Physical Properties.Solids, Liquids and Gases (States of Matter).For a general introduction to matter, visit the section on Matter in Bulk at the Wired Chemist. Matter is a general term that refers to anything that has mass and volume-in other words, physical objects. This competency looks at basic concepts in chemistry. The teacher understands physical properties of and changes in matter.
