Intermolecular Forces
Is the force that causes
the surface of a liquid to contract.
Surface Tension
in particular, has high surface
tension due to hydrogen bonds.
Water
affects surface tension
Temperature
is the ability of the liquid to flow
and/or the liquid’s resistance to flow
between the molecules of a liquid when they pass each other.
Viscosity
High resistance, ____ viscosity
high
_____ temperature, low viscosity
High
is the state change from liquid
to Gas, while the opposite is condensation.
Vaporization
tend to evaporate faster
than water.
Volatile liquids
The boiling point of water is?
100°C
is the formation
of liquid to gas with the addition of heat as
form of energy.
Molar heat of vaporization
is the amount of
heat needed to vaporize a given
amount of liquid at its boiling point.
