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

  • Melting of ice

  • Sublimation of naphthalene

  • Condensation of water

  • Dissolution of salt in water


B.

Sublimation of naphthalene

The order of entropy in solid , liquid and gas is gas > liquid > solid

Hence , in sublimation of naphthalene ,maximum increase in entropy is observed .
