When a gas is cooled, the particles begin to move more______(Quickly/slowly). When the temperature drops below the____ (melting point/boiling point), the substance's particles have condensed and formed a liquid. If the liquid is cooled down even more, the amount of thermal energy in the particles will____(increase/decrease), and the liquid's temperature will continue to decrease. Eventually, the substance will freeze and form a solid. If the temperature continues to
(Increase/decrease), the particles in the solid will____ (Vibrate in place/move around one another) more slowly.

Slowly; Boiling Point; Decrease; Decrease; Vibrate in place.

As temperature drops, so does thermal energy, and particle motion drops. The same trends in temperature, thermal energy, and motion applys to phases in decreasing order: gas>liquid>solid. The particle motion is always vibrations in place for solids because they are very tightly packed compared to liquids and gases.

The kinetic energy of the particles is directly proportional to the thermal energy of the system. The correct options are Boiling Point; Decrease; Decrease; Vibrate in place respectively.

Thermal energy and Particles:

  • The kinetic energy of the particles is directly proportional to the thermal energy of the system.
  • So when thermal energy is increased the kinetic energy of the particles is also increased.
  • Boiling Point: It is the temperature where the vapor pressure of the liquid is equal to the surrounding atmospheric pressure.
  • Since the particles of solid-state are bonded by a strong bond hence they vibrate in place when thermal energy is increased.

Therefore, the correct options are Boiling Point; Decrease; Decrease; Vibrate in place respectively.
