Nitrogen > Oxygen > Water >Alcohol> Salt > Sugar
Because Nitrogen has the smallest atomic mass, thus vibration of the N has molecules is greatest Same goes for the oxygen but it is heavier than Nitrogen Now Water and alcohol are both liquids but hydrogen bond in alcohol is greater than the water thus alcohol molecules form a heavy cluster which has low kinetic energy than water Sugar and salt are crystalline solids bit salts have ionic bonds and sugar is heavier than salts.

The decreasing order of kinetic energy, of the given substances is:
Water > Nitrogen > Oxygen > Alcohol > Salt > Sugar
This is because the kinetic energy decreases, with the increase in molecular mass of a substance.
(Here alcohol is assumed to be ethanol, which is the most common form).
