Chemistry unit 14 study guide
Intermolecular forces - including dispersion forces, dipole-dipole forces, and hydrogen bonds
- determine.... - correct answer-a substance's state at a given temperature
Intermolecular forces - correct answer-forces of attraction between molecules
The state of a sample of matter depends on - correct answer-temperature,IMF, and pressure
IMF stands for - correct answer-intermolecular forces
Stronger IMF - correct answer-the higher the boiling point and melting point, favors solid
state
More KE - correct answer-higher temp, favors gas
high pressure forces - correct answer-particles together favoring condensed states
In solids - correct answer-attractive forces outweigh kinetic energy of particles.
Particles stick together in rigid position
In liquids - correct answer-attractive forces are balanced by kinetic energy.
Particles stick together but can move past each other.
In gases - correct answer-kinetic energy outweighs attractive forces.
Particles fly rapidly past each other as if there are no attractive forces between them.
Particles have elastic collisions when they hit each other
Kinetic Molecular Theory (KMT) - correct answer-Explains the observed properties of matter
in its different states
KMT states that - correct answer-Particles are in constant, rapid, random motion.
The speed of this motion depends on temperature.
Collisions between particles are elastic.
No kinetic energy lost.
attractive forces - correct answer-Forces that hold particles of matter together
Electrostatic attractions - correct answer-In ionic compounds
Metallic bonding - correct answer-in metals
Covalent bonds - correct answer-between atoms
Attractive forces - correct answer-between molecules
