Answer : The correct option is (3) Evaporation.
Explanation :
Evaporation : It is a process in which the liquid particles are converted to gaseous particles. The inter-molecular forces of attraction between the liquid particles will be weakened. As a result the phase change occurs.
Freezing : It is a process in which a phase changes from liquid state to solid state.
Condensation : It is a process in which a phase changes from gaseous state to liquid state.
Crystallization : It is a process in which a solute particles get separated from the solvent in the form of crystals ( in solid phase).
Whereas in freezing, condensation and crystallization we are moving from one phase having weaker inter-molecular forces of attraction to another phase having stronger inter-molecular forces of attraction. So, in these processes strengthening of attraction between the particles takes place.
Hence, the correct answer is Evaporation.

120 grams of Carbon-14 decays to 15 grams in 17,190 years.
Answer:
0.967mole
Explanation:
Given parameters:
Volume of NH₄Cl = 21.67L
Unknown:
Number of moles = ?
Solution:
If we assume that the volume was taken at standard temperature and pressure,
Then;
Number of moles =
Number of moles =
= 0.967mole
