Q41 / 180 · COMEDK 2020 · Chemistry

In which of the following process, a maximum increase in entropy is observed?

A
dissolution of salt in water
B
condensation of water
Correct answer
C
sublimation of naphthalene
D
melting of ice

Solution

During sublimation of naphthalene, phase changes from solid to gaseous state. Hence, the randomness of the particles increases drastically. $\therefore$ It has maximum increase in entropy,

Hence, the correct answer is option: 'C'.
