Steady State Energy Equation Prof Akm Rahman CCBYNCSA Copyright by Prof Dr Akm Rahman Energy Equation for a control Mass and Control volume This is a Control Mass Approach where the quantity is fixed . (2.2)PHYSICAL PROPERTY. A physical property is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. . Viscosity, conductivity, malleability, hardness, melting point, boiling point, and density are examples of physical properties.. 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. 8/30/12. Chemical Property. - . The ability of a substance to . change . into another new . substance. - . This type of property . can only . be observed . through experimentation. - . Examples include flammable. 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.. 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. National 3 Unit 3 – Chemistry in Society. What are Properties?. Properties of materials are things that describe the appearance and characteristics of a material.. Examples of properties are:. Strong. Terri Ivory, MSN,RN,C. Effectively treating substance abuse among health care professionals it is important to understand the components of addiction. . The word addiction is often used as an umbrella term to describe a group of problems such as: . enquiries@alevelphilosophy.co.uk. 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. Intro to Matter. Matter. Matter- anything with mass and volume. Mass- how much matter (stuff) is in an object. Mass vs. Weight. Weight- measure of gravitational force. Objects with greater mass have a greater gravitational force so they weigh more. 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. 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: S8P1d. 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?
