UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: What are the differences between physical and chemical properties? Extensive properties Intensive properties Depends on the amount of matter present Volume, mass, amount of energy in a substance Does not depend on amount of matter present Melting point, boiling point, density, ability to conduct electricity and transfer energy as heat

UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: What are the differences between physical and chemical properties? Physical properties Chemical properties Characteristic observed or measured without changing substance Melting point, boiling point, color, size, ductility, malleable, density, ability to conduct heat or electricity Ability to change from one substance to a new substance Ability to produce a gas, burn, rust Example: Copper w/ moist air

UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: What are the differences between physical and chemical properties? Physical changes Chemical changes Change that does not change the identity or chemical makeup of the substance Cutting, melting, drawing into wire, crushing, temperature and pressure changes Substance changes into new substance b/c chemical bonds have been broken or made Occurs on molecular level Noticed by temperature change, smell/odor, bubbles (gas), rust formation Reactants  products

UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: What are the differences between physical and chemical properties? Law of Conservation of Mass Mass cannot be created or destroyed in ordinary chemical and physical changes Therefore, the mass before the reaction will be equal to the mass after the reaction
