anything that has mass and volume or

anything that has mass and takes up space

e.g., air and a balloon both have matter (mass and volume)
the space an object occupies

a measure of the size of a body or region in 3-dimensional space
three ways to measure volume
1) V = lwh (e.g., book)

2) graduated cylinders (liquids)

3) container it can fill (gas)
the quantity of matter contained in that object

a measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitational force
Name two physical properties that characterize matter.
Mass and volume
How does mass differ from weight?
Weight depends on gravity, while mass does not.

Mass measures the quantity of matter in an object [no matter where it is in the universe].

The weight of an object is the force produced by gravity acting on mass (the quantity of matter).
the force produced by gravity acting on mass.

a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe.
device used for measuring mass in a laboratory
the way scientists express forces
a quantity adopted as a standard of measurement

e.g., milliliters
something that has magnitude, size, or amount

e.g., volume
Systeme Internationale d'Unites

(length (meter), mass (kilogram), time (second), thermodynamic temperature (kelvin), amount of substance (mole), electric current (ampere), and luminous intensity (candela)
conversion factor
a ratio that is derived from the equality of two different units and that can be used to convert from one unit to the other
derived unit
Units that are derived by multiplying or dividing base units.
1L =
1000 mL = 1000 cm^3
1mL =
1 cm^3
physical property
a property that can be determined without changing the nature of the substance.

a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness.
The properties of a substance may be classified as:
1) physical
2) chemical
Describe table sugar (sucrose) using physical properties.
1) color--white
2) state--solid
3) gritty texture
4) melting point
5) boiling point

EX air -- colorless
Describe matter qualitatively
heavy, light, rough, and smooth

color, texture descriptions
Describe matter quantitatively
with numbers
the ratio of the mass of a substance to the volume of the substance; often expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases
density formula
density = --------
