Assertion (A). A liquid crystallises into a solid and is accompanied by decrease in entropy.
Reason (R). In crystals, molecules organise in an ordered manner.

Assertion (A): A liquid crystallizes into a solid and accompanied by decrease in entropy Reason (R): In crystals molecules are organised in an ordered manner.

Statement-1:A liquid crystallises into a solid and is accompainied by decrease in entropy. Statement -2: In crystals, moles cules organise in an ordered manner.

A liquid crystallizes into a solid then entropy will be

Adsorption of a gas on the surface of solid is generally accompanied by decrease in entropy. Still it is a spontaneous process. Explain.
