PPT-MECE-251 Thermo., Lesson 2: Properties of Pure Substances

R I T MECE251 1 A pure substance must have the same molecular composition throughout Water is a pure substance Air is not a pure substance In some cases dry air may be treated . By: Grant Mayberry. Introduction. The reason for doing this project was to figure out the mystery of who poisoned Buzz Lightyear. It all started with Woody & Buzz doing there new one and only cooking show, but somebody felt the need to poison Buzz. Now Buzz is in the hospital passed out and now its my job to find out who did it.. Intensive vs. Extensive. Essential Standard. 6.P.. 2 Understand . the structure. , classifications . and physical properties of matter.. Clarifying Objective. 6.P .. 2.3 Compare . the physical properties of pure substances that . Mrs. . aRusso. 8-1. Matter . Anything that has mass and takes up space.. It is the ‘stuff’ that makes up everything in the universe.. Properties of Matter. Hardness, texture, shape, temperature, flammability. Mixtures. Separation. of Mixtures. Atoms & Molecules. Matter. Pure Substances. Mixtures & Solutions. Compounds. E. lements. Heterogeneous. Homogeneous. Pure Substances. Definition:. A substance that cannot be separated by a physical or mechanical process, (by hand or with a tool).. 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. Divisions of Matter. Pure Substance. Cannot be broken down and retain its properties.. Has a fixed composition.. Every sample of a pure substance has EXACTLY the same composition AND exactly the same characteristics - homogeneous. Pure substances cannot be broken down by physical means.. Pure substances . contain . only one kind of molecule.. Molecules are small groups of atoms that make up matter. Example: Water is a molecule of two hydrogen atoms, and one oxygen atom. 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:. Objectives. PSc.2.1.1. . Classify matter as: homogeneous or heterogeneous; pure substance or mixture; element or compound; metals, nonmetals or metalloids; solution, colloid or suspension.. . Shoe Classification Activity. 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.. UEQ: How does the structure of matter influence its physical and chemical behavior?. LEQ: How is matter classified?. Bell Work 09/19/2012. Write question and answer.. Can you chemically break down an atom? Why or why not? . 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: Elements, Compounds, Mixtures All matter is made of atoms. Atoms are the smallest unit of an element that maintain the properties of that element. All matter can be classified as… Elements Elements are made of only one type of atom Purity, formulations and chromatography. Chromatography. Can be used to separate mixtures and help. identify substances.. Involves a mobile phase. (e.g. water or ethanol) and a stationary phase (e.g. chromatography paper). .
