classification of matter Flashcards
(22 cards)
Matter can be defined as
anything that has mass and takes up volume.
The mass of an object is the
measure of the amount of matter that makes up the object
The volume of an object is the
measure of the amount of space that the object takes up
if an object increases in temp it means
the particles vibrating speed has increased of the object
electrostatic forces
hold particles togeher, but there is a bit of empty space btwn them
The properties of a substance can help us
identify the substance
physical properties of a substance
can be measured or observed without involving chemical change to the substance
example of physical properties
- color
- odor
- size
- state5. solubility
- MP & BP
chemical properties of a substance
can be observed when it reacts with other substances
chemical properties describes
the ability of a substance to change into a new substance w diff properties
strength
the ability to stand up to forces being applied without bending, breaking, shattering or deforming
thermal conductivity
the ability to transfer energy or heat from one point to another
electrical conductivity
the ability to transfer electrical charge from a point of place to another
brittle
the ability of a substance to break or shatter easily
malleability
the ability to be shaped into a thin sheet or reshape without cracking
ductility
the ability to be drawn into a thin wire
magnetic
a material that is attracted by a magnet
non-magnetic
material that is not attracted to a magnet
density
amount of matter in a given space or volume
MP
the temp at which the solid form becomes a liquid
BP
the temp at which a liquid becomes a gas
MP & BP show the strength
of the AF btwn particles of a substance
