❌no spamming ❌​

Answer 1

#Hygroscopic:

=>A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.

#Deliquescence:

=>Tending to undergo gradual dissolution and liquefaction by the attraction and absorption of moisture from the air.

#efflorescence:

=>A process that occurs when something changes to a powder from loss of water of crystallization.

Answer 2

Answer:

Deliquescent: Deliquescent substances are solids that absorb moisture from the atmosphere until they dissolve in the absorbed water and form solutions. Efflorescent: Efflorescent substances are solids that can undergo spontaneous loss of water from hydrated salts
