Explanation:
Naphthalene undergoes sublimation easily i.e., the change of state of naphthalene from solid to gas without the intervention of the liquid state. Thus, naphthalene balls keep on forming naphthalene vapours which disappear into the air with time without leaving any solid.
The kinetic energy of the perfume particles is very high and hence, the rate of diffusion will also be high as kinetic energy is directly proportional to rate of diffusion.In other words,the higher the temperature, the higher the kinetic energy. ... That is the reason we can smell the perfume sitting several meters away.
