Answer:
CH3NH2 : Hydrogen bonding and London dispersion forces
F2 : Hydrogen bonding, dipole-dipole and London dispersion forces
NOF : Dipole-dipole forces
C2H6 : London dispersion forces
H2O : Hydrogen bonding and London dispersion forces
Increasing order of boiling point:
F2
C2H6
NOF
CH3NH2
H20
Explanation:
London dispersion forces exist in all substances
CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.
F2 : The bond is non polar because its a homonuclear bond
NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry
C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule
H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule
Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
Physical weathering is caused by physical processes such as changes in temperature, freezing and thawing, and the effects of wind, rain and waves.

I can't understand you what???

The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
