36 Terms
amorphous
without shape
crystalline
solid with a set of arrangements of particles
volatile
ease of evaporation
vapor pressure
pressure of the gas evaporating from the liquid
viscocity
resistance to flowing, because of stronger bonds
surface tension
attraction of molecules on the surface of liquid
sublimation
solid to gas
boiling point
point where the vapor pressure equals the atmospheric pressure, and liquid turns into gas
melting point
the temperature at which a solid will melt
evaporation
liquid to gas
deposition
gas to solid
condensation
gas to liquid
solution
a homogeneous mixture of a solute and a solvent
solute
what is being dissolved
solvent
what the solute is being dissolved in
saturated
a solution that contains the maximum amount of solute that can be dissolved at a given temperature and pressure
unsaturated
a solution that contains less solute than can be dissolved at a given temperature and pressure
supersaturated
a solution that contains more solute than is normally possible at a given temperature and pressure, achieved by cooling or evaporating
miscible
liquids that are mixable and will dissolve in each other
immiscible
liquids that do not mix or dissolve in each other
electrolyte
a substance when dissolved conducts electricity
non electrolyte
a substance that does not conduct electricity when dissolved in water
dissociation
solute separates particles(endothermic)
hydration
solvent particles surround solute(exothermic)
suspension
a heterogenous mixture where tiny particles are dispersed but do not dissolve
alloy
a solid solution of 2 or more metals, or a metal and another element
enthalpy
measurement of energy related to the law of thermodynamics
entropy
measure of how much the energy of atoms and molecules become more spread out in a process
endothermic
absorbs heat
exothermic
gives off heat
potential energy
energy that is stored up because of its position and forces acting on it
kinetic energy
energy in a object while in motion
mass% formula
mass of solute/mass of solution x 100
molarity formula
moles of solute/liters of solution
colloid
solution that over time, solute particles fall out of solvent
colligative property
characteristics of a solution that depends on the ratio of the solvent particles to the solute particles
