Properties of matter Flashcards
the amount of matter in an object
Mass
Mass is usually expressed in
Kilograms and grams
It is the measure of force that acts on an object.
Weight
Weight is expressed in
Newton (N)
It is the amount of space occupied by matter
Volume
It is the ratio between mass and volume.
Density
It is the ratio of a substance’s density to a standard substance.
Specific Gravity
Specific Gravity is…?
a dimensionless quantity.
These are qualities that are readily observable or measurable
without changing the matter’s composition.
Physical Properties
The nine physical properties
melting point
● boiling point
● freezing point
● solubility
● metallic properties
● size
● texture
● shape
● color
It is the temperature at which a
solid matter changes to liquid.
Melting Point
It is the temperature at which a
liquid turns into a solid matter.
Freezing Point
It is the temperature at which
liquid evaporates
Boiling Point
It is the ability of a solute to dissolve in a given
solvent.
Solubility
These are qualities that are observed specifically in metals.
Metallic Properties
These are qualities that are observed specifically in metals.
○ conductivity
○ malleability
○ ductility
It is the ability of a material
to allow heat or electric
charges to pass through
easily.
Materials can be ———– or
——- conductors.
Conductivity, Thermal, Electrical
It is the ability of a material to be
flattened into thin sheets.
Malleability
It is the ability of a material to be
easily drawn into wires.
Ductility
These are the characteristics that can only be seen when the
chemical identity of a material is altered.
Chemical Properties
Examples of Chemical Properties
biodegradability, combustibility,
flammability, and reactivity.
It is the capacity of a material to decompose through the actions of microorganisms.
Biodegradability
It is a chemical reaction between a substance (fuel) and oxygen which results in the generation of heat and Clight in the form of flame.
Combustion
It is the ability of a material to combust or burn.
Combustibility
