of matter offers a description of the microscopic properties of atoms or molecules and their interactions leading to observable macroscopic properties such as pressure volume and temperature.
Kinetic Molecular
44
an application of the theory is that it helps to explain why matter exist in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.
Kinetic Molecular
45
everything that takes up space and has mass, is the 'stuff' that makes up the cosmos. Atoms, which are made up of protons neutrons and electrons are the building blocks of all
Matter
46
is defined as everything that has mass and volume
Matter
47
what are the three primary states of matter?
Solid, Liquid, Gas
48
made up of particles that are constantly moving
Matter
49
they are spaces between particles of
Matter
50
this state is one of the fundamental states of matter
Solid
51
it differs from liquids and gases by the characteristics of rigidity
Solid
52
the molecules are tightly packed because of strong intermolecular forces they only oscillate about their mean positions
Solid
53
can be defined as the state of matter which has definite shape and volume and has a rigid structure
Solid
54
the molecules are closely packed due to weak intermolecular forces
Liquid
55
these forces are weaker than solids but stronger than that of gases
Liquid
56
there is much space between the molecules which makes their flowing ability easy
Liquid
57
it can easily acquire the shape of a vessel and they have fixed volume

69
two atoms are bound to each other through a polar covalent bond
Intramolecular Forces
70
dipole-dipole interaction
Intermolecular Forces
71
these are the forces that hold atoms together within a molecule
Intramolecular Forces
72
these are the forces that exist between molecules
Intermolecular Forces
73
types of intramolecular forces of attraction
Ionic Bond, Covalent Bond
74
this bond is formed by the complete transfer of valence electrons between atoms
Ionic Bond
75
it is a type of chemical bond that generates two oppositely charged ions
Ionic Bond
76
this bond is formed between atoms that have similar electronegativities affinity or desire for electrons
Covalent Bond
77
attractive forces that act between molecules or particles in the solid or liquid states
Intermolecular Forces
78
generally this attractive forces are much weaker than bonding force
Intermolecular Forces
79
the strength of this attraction is dependent on the arrangement of the particles the proximity of particles related to one another and the nature of the interacting particles
Intermolecular Forces
80
types of intermolecular forces
London Dispersion Forces, Dipole-dipole Forces, Hydrogen Bond, Ion-dipole
81
these forces are present between all types of molecules due to the movement of electrons
London Dispersion Forces
82
as electrons move around the nucleus and an even distribution causes momentary charge separations
London Dispersion Forces
83
slightly positive sides of a molecule are our tongue tied to the slightly negative sides of the adjacent molecules
London Dispersion Forces
84
the extent to which a dipole moment can be induced in a molecule is called its polarizability
London Dispersion Forces
85
the weakest of intermolecular forces that can exist between two molecules but the larger the atoms present the stronger the dispersion forces
London Dispersion Forces
86
attractive forces between polar molecules molecules that possess dipole moments
Dipole-dipole Forces
87
in polar molecules the electrons are unevenly distributed because some elements are more electronegative than others
Dipole-dipole Forces
88
the partial negative side of one molecule is attracted to the partial positive side of another molecule
Dipole-dipole Forces
89
this type of force is stronger than the dispersion forces because polar molecules have permanent uneven distribution of electrons
