delinquescence

Definition

1. Noun (uncountable):
   • The process of becoming liquid by absorbing moisture from the air: "delinquescence" is the property or act of a substance (especially a salt) to dissolve or liquefy by absorbing water vapor from the atmosphere.
   • Chemical deliquescence: In chemistry, the phenomenon where a solid substance becomes liquid due to its strong affinity for water, leading to the formation of a solution.

Usage Examples

• (The salt absorbs moisture and turns into a liquid.)
• (To avoid them absorbing water and dissolving.)

Advanced Usage

• "to undergo delinquescence": to experience the process of absorbing moisture and liquefying.

  • The compound undergoes delinquescence rapidly in tropical climates. (It becomes liquid quickly due to high humidity.)

• "delinquescence point": the specific humidity or temperature at which a substance begins to deliquesce.

  • The delinquescence point of sodium hydroxide is around 35% relative humidity. (The threshold for it to start absorbing moisture.)
