Vaporization
The change of state from a liquid to a gas (endothermic)
deposition
a gas changes directly to a solid (exothermic)
defeniton of intermolecular forces
attraction between different molecules
what happens to IMFS when boiled
bonds are broken (weakened)
condensation
conversion of vapor or gas to a liquid (exothermic)
Weakest IMF to the Strongest IMF's
dispersion, dipole-dipole, hydrogen bonding, and ionic bonds
baking bread
endothermic
evaporation of water
endothermic
melting ice cubes
endothermic
endothermic reaction
energy is absorbed
exothermic reaction
energy is released in the form of heat
candle flame
exothermic
condensation of rain
exothermic
making ice cubes
exothermic
Dispersion forces are stronger in molecules with a molar mass that is this.
higher
bond with the strongest IMF and a very high melting and boiling point
ionic bond
water is an...
ionic bond
Freezing
liquid to solid (exothermic)
Hydrogen bonds are strong due to high bonds of these types of molecules.
polar
triple point
represents the pressure and temperature at which all three states are in equilibrium.
critical point
represents the pressure and temperature at which liquid and vapor phases become indistinguishable.
sublmation
solid to gas(endothermic)
melting
solid to liquid (endothermic
When molecules have a high melting and boiling point, that means their IMF's are stronger or weaker.
stronger
