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

Law of Conservation of MassMass 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

UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do you properly measure and report the mass and volume?

Mass = kg, gA measure of amount of matter in an

objectUse triple beam balance or electronic scale

Volume = cm³, m³, mL, LA measure of size of a body or region in a 3-D shapeWater displacement

Density = g/cm³, g/L, g/mL, kg/L, kg/m³D=M/V
