Which of the following is in the correct order of boiling points for nano₃, ch₃oh, c₂h₆, and ne? a) ne < ch₃oh < c₂h₆ < nano₃
b) nano₃ < ch₃oh < c₂h₆ < ne
c) ne < c₂h₆ < nano₃ < ch₃oh
d) ne < c₂h₆ < ch₃oh < nano₃
e) c₂h₆ < ne < ch₃oh < nano₃

D

Explanation:

Me has the least boiling point because it has the weakest degree of intermolecular forces. The weak van Der Waals forces exist in C2H6. In CH3OH, there are strong hydrogen bonds which accounts for the higher boiling point. NaNO3 is an ionic compound, hence it has the highest boiling point among all the substances mentioned.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
