Transcript of Properties of Matter

Anything that has mass and takes up space!
Properties of Matter
Conductors
Heat and electricity move through them easily
Malleable
Ability to be hammered into different shapes
Ductility
Ability to be drawn (stretched) into a wire
High Density
Heavy for the size
How is a substance identified?
Physical and chemical properties can be used to classify and identify substances.

Metals and nonmetals are two major groups of elements that have different physical properties.
Heat and electricity do not move through them easily
Not shiny
Break or shatter easily (solids)
can be observed and measured without changing the kind of matter being studied.
Physical Properties
The following physical
properties can be used
to help identify a
substance:
The temperature at which a solid can change to a liquid.
Boiling Point
● The temperature at which a liquid changes from a liquid to a gas.
● Boiling begins when bubbles form throughout, grow larger, rise to the surface, and burst.
● As long as the substance is boiling the temperature of the liquid remains constant (at the boiling point).
● Boiling point is unchanging under constant conditions for a given substance.
● Example: The boiling point for pure water at sea level is 100o
C ( 212o
F).
The relationship between the
mass
of a material and its
volume

The density of a substance is always the same no matter how big or little the substance is●

Electrical conductors
allow current to flow easily.
Electrical

insulators
do not allow current to flow.
Color
● Color can be used to help identify a substance, along with other properties.
● By itself, color is not a significant identifier of a substance.
● Absence of color is also a physical property.
Hardness
● The relative resistance of a metal or other material to denting, scratching, or bending.
Magnetism
● The property of reacting to the forces exerted by magnets
Chemical properties
Chemical properties can be recognized only when substances react or do not react chemically with one another,
that is, when they undergo a change in composition
Ability to burn
The ability to burn involves a substance reacting quickly with oxygen to produce light and heat. This
process is called burning
Ability to rust
The ability of a substance to rust is a chemical property that involves a substance reacting slowly with
oxygen. The process is called rusting.
Performance Indicator
7.P.2B.1 Analyze and interpret data
to describe substances using physical properties (including state,
boiling/melting point, density, conductivity, color, hardness, and magnetic properties) and chemical properties
(the ability to burn or rust).
Study Jam

Luster
Having a shiny surface or reflecting
light brightly
Dull
Nonconductors
Brittle
Melting Point
Boiling Point
Density
Conductivity
Color
Hardness
Magnetism
This Study Jam gives an overview of density.
7.P.2B.2 Use mathematical and computational thinking to describe the relationship between the mass, volume,
and density of a given substance
A little more about density...
Density is the mass of a substance per unit of volume.
If mass= density/volume, what scientific tools do we need to find the density of an object?
Density is calculated using the formula: density = mass/volume
Volume (mL) can be calculated using basic math or the liquid displacement method.

Mass is measured in grams.
Get Started: Why does the diet coke float while the coke sinks?
This is why:
Boiling Point
The temperature at which a liquid can change to a gas.

Color
Color can be used to help identify a substance, along with other properties.
● Color by itself, does not identify a substance.

Hardness
The resistance of a metal or other material to denting, scratching, or bending.
Magnetism
The property of reacting to the forces caused by magnets.
Chemical Properties
Chemical properties can be seen only when substances react with another and form a
new

substance
.
Ability to Rust
Involves a substance
reacting slowly
with oxygen.
Ability to Burn

Involves a substance
reacting quickly
with oxygen to produce light and heat.
