The Kinetic-Molecular Theory
The theory that describes behavior of particles/gas in motion.
What is the Kinetic-Molecular Theory?
The attraction that dominates both dispersion and dipole-dipole forces.
What is hydrogen bonds?
A measure of the resistance of a liquid to flow.
What is viscosity?
A force per unit area.
What is pressure?
The phase changes that require energy
A collision where no kinetic energy is lost.
What is Elastic Collision?
A molecule that contains permanent dipoles.
What is Polar Molecules?
A solid in which the particles are not arranged in a regular, repeating pattern.
What is amorphous solid?
The SI unit of pressure
what is the pascal (Pa)?
The phase changes that release energy
What is freezing point, condensation, and deposition?
The chemists who proposed the kinetic-molecular theory to explain the properties of gases
What is Ludwig Boltzmann and James Maxwell?
Attractive forces that hold particles together in ionic, covalent, and metallic bonds within molecules
What is intramolecular forces?
An element that exists in different forms at the same state (solid, liquid, or gas).
What is an allotrope?
What is Dalton's law of partial pressures?
A graph of pressure versus temperature that shows in which phase a substance exists under different conditions of temperature and pressure
What is a phase diagram?
The equation that represents kinetic energy
What is KE= 1/2mv2 ?
Weak forces that result from temporary shifts in the density of electrons in electron clouds.
What is dispersion forces?
Law that states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass.
What is Graham's law of effusion?
One of these is equal to a force of one newton per square.
What is one pascal?
Where the temperature and pressure at which three phases of a substance can coexist
The attraction gas particles experience.
What is none?
The German-American physicist who first described dispersion forces.
What is Fritz London?
The smallest arrangement of atoms in a crystal lattice that has the same symmetry as the whole crystal.
What is unit cell?
One of these is equal to 760 mmHg or 706 torr of 101.3 kilopascals (kPa)
What is one atmosphere?
The six phase changes that can occur at the triple point
What is freezing and melting; evaporation and condensation; sublimation and deposition?
