properties of liquid Flashcards
is the tendency of a fluid to acquire
the least possible surface area.
surface tension
is the attraction between like molecules
Cohesion
is the attraction between unlike
molecules.
adhesion
is the measure of a fluid’s resistance to flow
Viscosity
what affects viscocity
Temperature
is the process where a fraction of the
kinetic energy of a liquid escapes from the surface to
enter the vapor phase.
vaporization
also called the
heat of vaporization, is the heat required to induce
this phase change.
enthalpy of vaporization
Vaporization occurs more readily with:
- increased temperature
- increase surface area of a liquid
- decreases strength of intramolecular forces
is the pressure exerted by a vapor in
equilibrium with its liquid phase in a closed system
Vapor pressure
refers to the ability of a substance to
dissolve in a given amount of solvent at a specified
temperature.
solubility
● If two liquids dissolve or mix together, they are called….
Miscible liquids
If two liquids do not dissolve or mix together, they are
called
immiscible liquids
Substances or molecules that form interactions with
water are also described as
hydrophilic
Substances or molecules that repel water are
described as
hydrophobic
Molecules with both hydrophilic and hydrophobic
regions are known as
amphpathic molecules
