5.) As temperature increases the average kinetic energy of the particles increases. Phase of matter is determined by the strength of intermolecular forces. As the average kinetic energy goes up the ability to overcome the attractive forces increase.
7.) a) London Dispersion Forces b) dipole-dipole & LD forces c) dipole-dipole & certain cases Hydrogen bonding.
a9) Br2 is a nonpolar covalent molecule so only london dispersion forces must be overcome to convert the liquid to a gas.
9b) CH3OH is a polar covalent molecule that experiences
