PPT-Physical and Chemical Changes

17 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. #1: What happens to a substance when a chemical change occurs?. #2: What are some signs of a chemical change?. Bell Ringer: Tuesday 10/1/13. Read the paragraph below and determine the main idea. Then, write and answer the questions. Mrs. Lowe . April 2011. Chemical changes . Chemical change . is a change that forms a new type of matter . Chemical property . is a feature of matter that can cause a chemical change. Examples of a different type of matter forming during a chemical change. 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.. 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.. 1-12-16. Bell Work 1-12-16. When air is heated, it expands and rises. Hot-air balloon pilots use this phenomena to their advantage. These pilots use a gas-flame blower to increase the temperature of the air inside the balloon making the balloon rise. . Navo. Middle School Science. Physical Change. A change in the size, shape, form, or state of matter that does not change the matter’s identity.. Examples:. Play-doh. being sculpted. Ice Cream melting. 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. Science . Fifth Grade. Mr. Pate. Standards. S5P2. . Students will explain the difference between a physical change and a chemical change. . a. Investigate physical changes by separating mixtures and manipulating (cutting, . EQ: How are changes in matter related to changes . in energy?. Changes in Matter. You are at the beach. You built a sandcastle!. You notice storm clouds gathering in the distance.. You are sad : (.

Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility) How are physical and chemical properties different? 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. Objectives. Compare chemical reactions to physical changes. Compare parts of an atom. Calculate the mass of one mole of an element or compound. Explain how ionic and covalent bonds are formed. Identify the parts of chemical equations.
