The word "kinetic" refers to this idea.
Motion
Any substance that flows is called a
fluid
In solids, the IMFs are very (strong/weak).
strong
At a low temperature, gas particles move slowly, so the pressure is (higher/lower).
lower
Attractive forces between already-existing molecules are called
Intermolecular Forces
This is the theory that states that all matter is in constant motion.
Kinetic Theory or Kinetic Molecular Theory
What two states of matter are considered fluids?
gas and liquid
hydrogen bonds
Increase
Intermolecular forces are different from intramolecular forces because intramolecular forces are the forces that hold ______ together to form molecules.
atoms
How would we describe the collisions of gas particles?
The collision of gas particles is perfectly elastic.
Liquid particles are ________ to one another, which is what makes liquids different from gases.
attracted
____________ solids are the strongest type of crystalline solid.
covalent network solids
If more particles are added to a vessel, the pressure will (increase/decrease) because more particles = more collisions.
increase
The strongest IMF is the
hydrogen bond
What are the values for standard temperature and standard pressure when a gas is at STP?
When particles have freedom of motion, what happens?
Particles can rapidly move to replace another particle.
True or False? Ionic solids conduct electricity in their solid state.
False
1 atm = _____ kPa = _______ mmHg
101.3 kPa and 760 mmHg
Hydrogen bonds exist when hydrogen is bonded to the following 4 elements.
Fluorine, chlorine, nitrogen, or oxygen
I would expect the bonding in ammonia (NH3) to be
polar covalent
What helps us explain the behavior of different substances and states of matter?
Identifying patterns in the strength of attractive forces within the matter.
Metallic solids differ from ionic solids because metallic solids are made up of (atoms/ions/molecules), and ionic solids are made up of (atoms/ions/molecules).
atoms; ions
203.7 kPa = _________ atm
2.01 atm
This is the IMF that happens when a nonpolar molecule becomes polar temporarily.
Dispersion forces
