PPT-Chemical (+ Physical) Properties

Science 9 Review Physical Properties Characteristics of substances that you can sense touch see smell etc These do not change the identity of the substance Does NOT change the identity Chemical Properties. Chemical Property. something that leads to a change in composition of matter. Flammability –. ability to burn when oxygen is present. Can be a good and bad property (lighter fluid SHOULD be flammable, Carpet is bad to be flammable). (2.2)PHYSICAL PROPERTY. A physical property is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. . Viscosity, conductivity, malleability, hardness, melting point, boiling point, and density are examples of physical properties.. Chapter 1. Barbara Mowery. York College. Apple juice is an . example. of . a(an). element.. compound.. homogeneous mixture.. heterogeneous mixture.. Apple juice is an . example. of . a(an). element.. How to tell the difference. Physical properties. Inherent characteristics of a substance that can be determined without altering its composition. Associated with its physical existence. Color, taste, odor, state of matter (solid, liquid, or gas), density, melting point, boiling point.. TEK 5.5 A – Students will classify matter based on physical properties…. Matter. Matter. is any living or non-living thing in the universe. All objects, things, plants, people, animals, etc are made up of matter. Physical and chemical changes. I. Physical change. A. Does not change the matter. Thermal conductivity. : the rate at which a substance transfers heat. State. : the physical form in which a substance exists, such as solid, liquid or gas. Property. Is a description of an object. The tree is TALL. The tree is GREEN. If struck by lighting, the tree could catch FIRE (BURN). Physical Properties. Are determined by the use of the . . . . . Physical and Chemical Properties. . Physical and Chemical Changes. Chemistry. – the study of matter. its composition, structure, and properties. its transformations – both chemical and physical. Physical Property. Physical property = a characteristic of matter that can be . observed or measured . without changing the identity of the substance. . Ex: . mass volume . density hardness. color malleability. Describing Matter. Extensive Properties: depend on amount of matter in a sample. Mass: amount of matter. Volume: space occupied. Intensive Properties: depend on type of matter, not amount. Density: mass/volume. S8P1d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility) How are physical and chemical properties different? Physical and Chemical Changes Physical and Chemical Properties Everything around us has physical and chemical properties. Physical Properties Characteristics you can observe without changing the substance into something new. Changes or transforms chemicals into . other. chemicals. Ex: Iron + Oxygen . . Iron Oxide (rust). Physical Science Review. What is the product?. What are the reactants?. Chemical formula. . shows the kind and proportion of atoms of each element that occurs in a particular compound. and. Physical Properties. . Observations that . DO NOT CHANGE . the substance or mixture. Measure. See. Smell. Hear. Touch. Taste. Chemical Properties. Describes how the substance or mixture will react with another.
