Physical Properties9/26

I.STARTER

What would your definition of a physical property be? Give me an example of what you mean.

II. PRACTICEPHYSICAL & CHEMICAL PROPERTIES

OF MATTER

MATTER

Anything that has mass and volume (takes up space).

Can exist in 4 states: solid, liquid, gas, and plasma

PHYSICAL PROPERTIES

Properties that can be determined without changing the substance into a new kind of substance.

BOILING POINT

The temperature at which a substance changes from a liquid to a gas.

MELTING POINT

The temperature at which a substance changes from solid to a liquid.

DUCTILITY

The ability to be pulled into a wire.

MALLEABILITY

The ability to be pressed or pounded into a thin sheet.

CONDUCTIVITY

The ability the substance has to allow electricity to flow through it.

SOLUBILITY

The ability to dissolve in another substance.

OTHER EXAMPLES OF PHYSICAL PROPERTIES

Color

Transparency (ability to let

light pass through)

Odor

Mass

Volume

Texture (smooth, slick, rough)

State: (Solid, Liquid, Gas)

Luster - Shiny or Dull

Metal or Non-Metal

elasticity (ability to

stretch)

Density

APPLICATIONDENSITY

The amount of matter in a given volume

FORMULA: D =

M V

UNITS FOR DENSITY G/CM3 OR G/ML

Formula:M = mass V= volume D = density

MOVEDM=mass O=over V= volume E=equals D= denisty

III. APPLICATION

Find the density:

Set up your density problems like this:

Use the Triangle

Given: Mass = 35 grams Unknown: Density (g/ cm3) Volume = 7 cm3

Formula: D = M / V Solution: D = 35g/7 cm3

D = 5 g/cm3

Ex. If the mass of an object is 35 grams and it takes up 7 cm3 of space, calculate the density.
