22. At the boiling point, particles throughout the
liquid have enough kinetic energy to
vaporize.
23. Liquid B would evaporate faster because it
has a higher vapor pressure, which indicates
that it is more volatile
24. Evaporation leads to cooling of a liquid
because the particles with the highest kinetic
energy tend to escape first. The remaining
particles have a lower average kinetic energy
and a lower temperature.

23. According to the kinetic theory the motion of
the particles in a gas is constant and random.
Because the particles are relatively far apart,
no attractive or repulsive forces exist between
the particles. They move independently of
each other and travel in straight line paths
until they collide with one another or other
objects.
24. Odors travel long distances from their
sources.

24. When a solid is heated, its particles vibrate
more rapidly as their kinetic energy increases.
Eventually, the disruptive vibrations of the
particles are strong enough to overcome the
attractions that hold them in fixed positions.
The organization of the particles within the
solid breaks down and the solid becomes a
liquid.

21. Solids that have a vapor pressure that exceeds
atmospheric pressure at or near room
temperature can change directly to a vapor.
This process is called sublimation.
22. The temperature of the system remains
constant while the change of state is
occurring.
