Which process most likely takes place when the kinetic energy of molecules overcomes the intermolecular forces?
a) boiling
b) condensation
c) freezing
d) solidification

a) boiling

Explanation:

The major difference between solids, liquids and gases is:

a) intermolecular forces [ the order is solid>liquid>gas]

b) kinetic or thermal energy. [the order is gas>liquid>solid].

thus when the kinetic energy is more and intermolecular forces are less it means there is a change from

i) solid to liquid

ii) solid to gas

iii) or liquid to gas

the given processes observe following phase changes:

a) boiling : liquid to gas

b) condensation : gas to liquid.

c) freezing : liquid to solid.

d) solidification:liquid to solid.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
