IMFs
strongest intermolecular force
hydrogen bond
three properties of solid
fixed volume, little particle motion, high density
this force (or property) causes the surface of a liquid to behave like a stretched film
surface tension
when particles lose energy and lock into fixed positions, this phase change occurs
freezing
happens when the vapor pressure of a liquid equals atmospheric pressure
boiling
these weak forces exist in all substances and are caused by temporary fluctuations in electron density
dispersion forces
What does the strength of a crystal depend on?
charge magnitude, particle size, geometric structure
ability to spread throughout and mix with another fluid
diffusibility
phase change occurs when liquid turn to gas relatively rapid
boiling
water boils at this temperature at STP
100 degrees Celsius
polar molecules attract each other through this intermolecular force
dipole-dipole forces
Unlike most substance, this compound is less dense as a solid than as a liquid.
water
occurs when molecules of different substances attract each other
adhesion
gas becomes a liquid
condensation
What is boiling affected by?
intermolecular forces, temperature, pressure
All substances experience this type of intermolecular force
dispersion
The structure of a crystal depends on the number, type, size, and ________ property of particles.
electrical charge
If a liquid has high cohesion, then is it more or less viscous. What is viscosity?
more, liquids ability to resist flow
this occurs when molecules at the surface gain enough energy to escape into the vapor phase
evaporation
Pressure that is exerted by evaporated particles over a liquid
vapor pressure
intermolecular forces are much weaker than this type of bond within molecules
intramolecular, covalent, ionic
particles are arranged randomly rather than in a regular pattern, type of solid
amorphous solid
Water rises in this tubes because of adhesion and this penomenon.
capillary action
when solid turns directly into gas
sublimation
Vapor pressure increases as this property increases.
