PPT-Platonic Solids

Describe these objects What are some things that you notice Have you ever seen anything like these Where What do they remind you of How would you describe these objects How can we describe these using geometric terms. Module 1. Session Topics. Surfaces and Solids of Revolution. Degree of Revolution. Hollow Objects. Visualizing Revolution. Surfaces and Solids of Revolution. Surfaces and Solids of Revolution are formed when a 2-D shape is revolved about an axis. J. Blackmon. Platonic Forms. Platonic Forms. The Problem. We encounter particular instances of justice, but how do we come to know justice?. We encounter particular triangles, but how do we come to know about . Different mixing action. Mulling is smearing or rubbing action similar to that in mortar and pestle. Wide, heavy wheels of the mixer did the same job. Pan is stationary & central vertical shaft is driven – causing the . MATH 420 Presentation: Kelly Burgess. What are they?. Convex Polyhedron (polyhedron: 3d solid with straight edges and flat faces). All faces are congruent. Same number of faces meet at each vertex. Named after Greek philosopher Plato who associated each with a basic "element". ● . Phases and Phase Diagrams. ● Liquids and Liquid Properties. ● Intermolecular Forces. ● Heating Curves. ● Introduction to Solids. ● Cubic Packing Arrangements. ● Closest-Packed Structures. Jim Olsen.

Department of Chemical Engineering,. University of Engineering & Technology Lahore . Intermingling of two or more separate components to form more or less uniform product. . Some other terms are. By the end of the lesson you should know. The names of the states of matter. That matter is made of particles. How the particles are arranged in solids liquids . and gases. The names of the changes of state. SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . Grade 9 Math. Platonic solids. E4 Make and apply generalizations about the properties of platonic solids. To prepare for this lesson. What is a polygon? . What are some polygons you know?. What is a regular polygon?. Beaker. USE:. Holds solids or liquids. Poor accuracy- only estimates volume. Hot Hands. USE:. Use to hold beakers when warm. Should not be used when liquid is boiling. Graduated Cylinder. USE:. Measure volumes of liquids. Lecture Presentation. Classifying Solids Based on Bonds. Metallic solids. are held together by a “sea” of collectively shared electrons.. Ionic solids. are sets of cations and anions mutually attracted to one another.. All . faces, all edges, all corners, are the . same.. They are . composed . of . regular 2D polygons:. There were infinitely many 2D n-. gons. !. How many of these regular 3D solids are there?. Making a Corner for a Platonic . E-mail: . benzene4president@gmail.com.
