L1 - Properties of Matter Flashcards
(38 cards)
is a branch
of natural science that deals
principally with the
properties of substances,
the changes they undergo,
and the natural laws that
describe these changes.
Chemistry
is the chemistry of substances that do not
contain carbon combined with hydrogen.
Inorganic Chemistry
is the chemistry of carbon compounds.
Organic Chemistry
is concerned with the separation,
identification of substances present in a sample
(qualitative analysis) or with the amount of each
that is present (quantitative analysis).
Analytical Chemistry
involves the study of the mathematical
theories and methods of physics to the properties
of matter and to the study of chemical processes
and the accompanying energy changes.
Physical Chemistry
is the study of the processes in living organisms.
Bio Chemistry
is the study of sub-atomic particles and nuclear reactions.
Nuclear Chemistry
under extreme conditions, other states exist such ___ can form
Bose-Einstein Condensates.
If the atoms of a solid are
arranged in repeating and
orderly pattern it is called a
crystalline solid
The repeating pattern in crystalline solid is
called
crystal lattice.
A solid with atoms that are
not arranged and lack of order is called
amorphous solid
BEC is named after
Satyendra Bose/Albert Einstein
These two scientists made the first BEC using supercooled gas rubidium (Rb) atoms.
Eric Cornell and Carl Wieman
refers to
quality of substance that can
be observed or measured
without changing the
composition of the substance.
Physical Property
property refers to the physical property
that does not depend on the amount of
substance involved.
Intensive Property
this property refers to the
physical property that depends on the
amount of material examined, such
as volume, mass, size, length, and
weight.
Extensive property
the richness of visual appearance/refers to amount of light reflected
color
the shine or glow of a material
Luster
the rigidness and resistance to pressure
hardness
a distinctive smell
odor
can transmit heat, electricity, or sound.
conductivity
can be dissolved in a solvent
Solubility
can be molded or bent into different
shapes (plasticity) – into thin sheets under pressure
Malleability
can be pulled or stretched as a thin wire.
Ductility
