PPT-Identification of Substances by Physical Properties

Lab work4 of Chemistry 1411 Classification Develop critical thinking using a realworld scenario activity with students playing the main role Aiden Eblimit PhD Adjunct Chemistry Instructor. 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.. 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.. Types of Separation. Mechanical Means of Separation. Density Separation. Centrifugation. Non-Mechanical Means of Separation. Chromatography. Distillation. Froth Flotation. 2.3 Separating the Substances in a Mixture. 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. Russell Yost, Ph.D.. Department of Tropical Plant and Soil Science. University of Hawai`i at . Manoa. Particle size determination in Soils of the Tropics. Some weathered soils of the tropics – those containing large amounts of hydrous . 6.P.2.3. Warm Up . This is an example of matter; . Can you identify it?. How would you classify it?. Think of ways scientists could classify different types of matter?. Classification of Gold. At room temperature. 1. Cohesive behavior.. 2. Ability to moderate temperature. 3. Expansion upon freezing.. 4. Versatility as a solvent. Nature of Water . . Polar Molecule Hydrogen Bonds. 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?. How can matter be classified?. Atoms . are the smallest unit of an element that maintains the properties of that element.. The most basic ingredients to . all . matter. Atoms can be combined in three majors ways:. enquiries@alevelphilosophy.co.uk. © Michael Lacewing. Substance and properties. A substance is an entity, a thing, that does not depend on another entity for its continued existence. . It has ‘ontological independence’. th. Grade Science. What are “Substances”? . Substances can be identified as either…. Elements. Compounds. Mixtures. So, what is a substance?. A substance cannot be further broken down or . p. urified by physical means.. I can classify pure substances. . This means that I know the difference between an element and a compound.. I can describe the characteristics of an element. . This means that I know how elements are identified by using chemical symbols.. 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. Currently at Universit
