PPT-Physical and chemical properties

Physical Science Notes Physical Properties PHYSICAL PROPERTY A feature or characteristic of matter which can be observed without changing the identity of the matter  Examples Color. (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.. 1.7. Physical Changes. Physical Change. : the substance involved remains the same, even though it may change state or form. . Examples: . Dissolving – stirring a spoonful of sugar in water. Melting –an ice cube melts. Matter. Every element/compound is unique in some way from all others.. If you know enough about a substance, you can figure out what it is.. If you know what a substance is, you can know all types of things about it.. 8/30/12. Chemical Property. - . The ability of a substance to . change . into another new . substance. - . This type of property . can only . be observed . through experimentation. - . Examples include flammable. 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.. Matter. All matter has two types of properties: . Physical properties . Chemical properties. Physical properties. A . physical property . is a characteristic of a substance that can be observed without changing the substance into another substance.. 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 . . . . observations. about the mystery material.. Think about whether these observations could be physical or chemical properties. You will be given a detective’s kit, consisting of:. Vinegar (an acid). pH strips. 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. Changes. The Difference. Physical Change . – . matter changes form . but is still made of the same molecules, typically . reversible. Chemical Change . – a . change in the molecules . occurs, . cannot be reversed. 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.
