PPT-Physical versus Chemical Properties

Chapter 2 Section 2 Describing matter Matter anything that has mass and takes up space Mass the amount of matter in something Volume the amount of space something occupies Which of the following is matter. 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). 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. and. Changes. By Jordan Parkinson. What are some Physical Properties?. Appearance – O. utward . or visible aspect of a person or thing. . Color - A. . visual attribute of things that results from the light they emit or transmit or reflect. 21. Physical Properties. Chemical Properties. Physical Change. Chemical Change. Chemical and Physical Changes Brain pop. Physical Properties. can be observed or measured without changing the substance.. Blue Color. Blue Color. Physical property. Density. Density. Physical property. Flammability. Flammability. Chemical property- The original substance is fundamentally changed. . Solubility- (dissolves into a liquid to make a solution). 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. 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 . . . . 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. 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. Density. A liquid becomes a gas. .. Burn bacon in the pan. .. Magnetic. Bake . cupcakes. Burning . leaves. Reactivity. Blue Station. Define the following terms.. Matter. Physical Change. Chemical Change. mATTER Anything that has mass and volume (takes up space) Exists usually as a solid, liquid or gas (the fourth state is plasma) Characteristics (Properties) of Matter Matter has many characteristics (properties) that can be observed: 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.
