  3. Aquello que tiene masa y ocupa un espacio es MATERIA FUNDAMENTALES presenta PROPIEDADES CUANTITATIVAS o MAGNITUDES FÍSICAS PROPIEDADES CUALITATIVAS pueden ser • No dependen de otras: • Longitud (m) • Masa (kg) • Tiempo (s) • Temperatura (K) se pueden • No permiten identificarlas • No se pueden medir Comparar con un patrón DERIVADAS es MEDIR GENERALES ESPECÍFICAS de forma Dependen de tras: velocidad (m/s) Densidad (kg/m3) DIRECTA INDIRECTA No identifican la sustancia: Temperatura/ masa/volumen/ Superficie (etc.) Sí la identifican: densidad/ PF / PE/ Con un instrumento: longitud/tiempo/ Velocidad/etc. A partir de una fórmula: volumen/superficie

  5. STATE CHANGE GRAPH

  6. VOCABULARY: STATE CHANGES • Vaporization: is the state change from liquid to gas. • Evaporation: is the state change from liquid to gas. It happens at room temperature and only on the surface of the liquid. The rate of evaporation increases when the temperature increases. • Boiling (also called ebullition): is the state change from liquid to gas at a constant temperature. All the liquid changes state and while it happens, the temperature doesn’t change. • Condensation: is the state change from gas to liquid. • Boiling point: is the temperature at which a liquid boils. It is different for each substance. Boiling point = Condensing point

  7. VOCABULARY: STATE CHANGES • Freezing: Is the state change from liquid to solid. • Melting: Is the state change from solid to liquid. • Melting point:Is the temperature at which a solid turns into a liquid. It is different for each substance. Melting point = Freezing point • Sublimation: Is the transition from solid to gas. • Deposition: Is the state change from gas to solid.

  8. Are made up by two or more substances at not fixed proportions • They can be separated by physical methods MATTER • A sample of matter that consists of only one component. PURES SUBSTANCES MIXTURES HOMOGENEOUS MIXTURES HETEROGENEOUS MIXTURES COMPOUNDS SIMPLE SUBSTANCES • They are made up by two or more elements combined in a fixed proportion • The properties of a compound are completely different that their elements. • We can break down by chemical means • They have uniform composition • and properties • throughout • We cannot see their components with a naked eye • They do not have uniform composition and properties throughout • We can see their components • They are made up by atoms of the same element • We cannot break down in any way

  13. SEPARATING MIXTURES: CRYSTALLIZATION concentration filtering cristallization

  14. SEPARATING MIXTURES: DISTILLATION termometer colector colector water distillation flask distilled Cold water Erlenmeyer flask

  15. VOCABULARY: SEPARATING METHODS • Sieving: Consists of separating larger pieces of something from smaller pieces. • Magnetization: separating a substance, like iron, using a magnet. • Filtering: method of separation that is used for separating insoluble solids from liquids. • Decanting: consists of separating two immiscible liquids of different densities. • Crystallization: Process that consists of obtain a solid dissolved in a liquid by evaporation of liquid. • Distillation: is a method of separating substances based on differences in their boiling points. This method is used to separate a liquid from the solution. The other components can be solids or liquids.
