Intermolecular Forces
This type of intermolecular force is present between hydrogen and oxygen, nitrogen, or fluorine
What is hydrogen bond
The molecules in this kind of solid are arranged randomly, without any organized structure or pattern
What is an amorphous solid
This word refers to liquid's ability to resist flowing because of the strength of its intermolecular forces
What is viscosity
This is the process of a solid turning into a liquid
What is melting
Dry ice turns into a thick smoke when it is exposed to room-temperature air. State which process is occurring.
What is sublimation
This type of intermolecular force is present between two polar molecules
What is a dipole-dipole force
The molecules in this kind of solid are arranged in an orderly, repeating matter
This is the process by which two liquids can be separated from one another
What is distillation
This is the process of a liquid turning into a solid
What is freezing
You are playing basketball outside and your sweat helps keep your body cool. Say what is happening to that sweat.
What is evaporation
This type of intermolecular force is present between two molecules that are non-polar
What is a London dispersion force
Some substances form into different kinds of crystals. These different crystals are called _________.
What are allotropes
This is the point at which the kinetic energy of a liquid causes its pressure to exceed the atmospheric, or applied, pressure.
What is a boiling point
These are the words used when a liquid turns directly into a gas, or vice versa.
What are sublimation and deposition
Water evaporates slowly from a jar, but the water level stays consistent once you put a lid on the jar. Describe what is happening inside the jar.
What is dynamic equilibrium - the processes of evaporation and condensation evening out.
Dispersion forces are stronger between molecules that are ______.
What is larger/bigger
This word is used to describe atoms or molecules that can form into more than one type of crystalline solid
What is "polymorphous"
_______ _______ is a thin "skin" that forms on top of water because the strength of the hydrogen bonds in the water result in an imbalance of forces.
These are the two words used to describe a liquid turning into a gas
What is evaporation and vaporization
What is intermolecular forces weakening (due to increased kinetic energy)
In non-polar molecules, temporary poles are formed by this.
What is the random orbit of electrons clumping together
_______ ______ is energy released when gaseous particles form crystals.
What is lattice energy
This word refers to a curved surface that forms on top of a liquid within a container
What is a meniscus
This is the point at which a substance can simultaneously exist as a solid, liquid, and gas
What is a triple point
When the atmospheric pressure decreases, this happens to the boiling point of a liquid
What is decreases
