Matter Flashcards
is anything that has mass and volume.
Matter
is the amount of matter contained in an object.
Mass
is the amount of space an object occupies.
Volume
what are the three states of matter?
solid
liquid
gas
Describe Solid
has mass
occupies exact space
has a definite shape
does not flow
describe Liquid
has mass occupies
exact space
has no definite
shape; follows the
shape of container
flows easily
Describe gas
has mass does not occupy exact space
has no definite shape; takes the shape of the
container
flows fast and easily
matter is made up of tiny particles known as
atoms
SOLID, LIQUID, GAS
do not have a regular arrangement.
LIQUID
SOLID, LIQUID, GAS
have a fixed arrangement of atoms.
SOLID
TRUE OR FALSE
fixed arrangement of atoms in solids makes them hard and rigid
TRUE
TRUE OR FALSE
SOLID DOES NOT HAVE DEFINITE SHAPE
FALSE
SOLID LIQUID GAS
are held by a strong force which makes them compact.
SOLID
SOLID LIQUID GAS
There is very little space between the particles.
SOLID
SOLID LIQUID GAS
does not have a definite shape. Instead, it follows the shape of their container.
liquid
what happens when liquid spills
it spreads over a surface and flows towards its lowest point.
SOLID LIQUID GAS
they flow or spread out easily.
liquid
SOLID LIQUID GAS
particles do not have a fixed arrangement
GAS
SOLID LIQUID GAS
Because of the greater distances between gas
particles, they tend to move rapidly in different directions.
GAS
SOLID LIQUID GAS
do not have a definite shape and volume.
GAS
__________are highly compressible
GAS - The greater spaces between gas
particles allow them to be compressed.
A ___________________ has a definite composition and a unique set of properties.
PURE SUBSTANCE
A pure substance made up of only one kind of atom is
ELEMENT
EXAMPLE OF ELEMENT WITH ONE ATOM
helium, sodium, gold, and copper
true or false
There are more than a thousand of naturally existing and artificially made elements.
false
is a chart that summarizes the different elements found on Earth.
periodic table of elements
A _________________is composed of two or more elements that are chemically combined.
compound
true or false
Two or more elements undergo a physical reaction or a rearrangement of atoms
to form compounds.
false - two or more elements undergo chemical reaction to form compound
is a shorthand way of writing compounds.
chemical formula
a process that splits the molecule of water with the aid of electricity.
electrolysis
___________________consists of two or more pure substances that are physically combined.
mixture
___________mixture has a uniform appearance.
homogeneous
what are the 2 parts of solution
solute
solvent
it is the dissolving medium in a solution
solvent
the substance being dissolved
solute
homogeneous , heterogenous
is a non-uniform mixture.
heterogenous
the components of this mixture can be easily
identified as it forms two phases.
heterogenous
what are the 2 kinds of heterogenous mixture
suspension
colloid
is a mixture that has suspended particles in a liquid that settle eventually.
suspension
is a heterogeneous mixture that is composed of two different phases in which particles of one substance are dispersed or distributed to another substance.
colloid
