Physical and Chemical Properties
Alike? Different? • Draw a double bubble map in your notes to compare and contrast physical and chemical properties.
Properties of Matter-Words to Know…
Matter Anything that has mass and takes up space!
Mass • A measure of how much matter is in an object.
Weight • A measure of the force of gravity on an object.
Volume • The amount of space that matter occupies.
Density • The measurement of how much mass of a substance is contained in a given volume. • Mass/Volume • I Density
States of Matter • There are different “states” of matter. No, not like Texas, Oklahoma, New Mexico. States of matter are also known as phases (a physical state of matter). Elements and compounds can move from one phase to another phase when special physical forces are present. • Solid • Liquid • Gas
Solids • Definite volume • Definite shape
Liquids • Definite volume • No definite shape
Gases • No definite volume • No definite shape – Take the shape of their containers
Freezing point • The temperature at which a liquid changes into a solid. The freezing point of water is 0 Celsius
Boiling point • The boiling point of an element or compound means the temperature at which the liquid form of an element or compound is at equilibrium with the gaseous form. • the boiling point of water is 100 degrees Celsius.
Melting point • The temperatures at which the solid form of the element or compound is at equilibrium with the liquid form. • Basically the range at which the solid changes its state • The melting point of into a liquid. water is 0 degrees Celsius MP=FP!
Compound • A substance made of two or more elements chemically combined in a set ratio. – Water and salt are 2 examples of compounds.
Mixtures • A mixture is a physical blend of two or more substances that are not chemically combined – Salt & Water – Sand – Rocky road ice cream
Homogenous Mixtures • Evenly distributed, uniform in composition, – Components are not visible discernable • Salt water
Heterogeneous Mixtures • Mixture that is not uniform in composition – Parts easily discernable
All substances have properties… Including people! Example: People can be identified by their … Face (shape, Voice Height Finger prints Teeth DNA expressions) Eye color Hair color
What are properties? • Matter has observable and measurable qualities. • We can use general properties to identify substances. • Two basic types of properties of matter: Physical properties and Chemical properties:
Physical Properties • Physical properties are used to identify, describe and classify matter. – Characteristic of a substance that can be observed (using your senses) without changing the substance into something else. Hardness Texture Color Odor Taste Temperat ure
More EXAMPLES Physical • size, shape, freezing point, boiling point, melting point, magnetism, viscosity, density, luster and many more. – Viscosity - The resistance of a liquid to flowing. – Examples: – Low viscosity-water, rubbing alcohol – High viscosity-honey
Chemical Properties • Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up. Flammability Rusting Creating a Reactivity with new chemical water product Creating gas bubbles p. H
