Change of a liquid into gas at any temperature below its boiling point is called:

  1. Acrystallisation
  2. BevaporationCorrect
  3. Cdeposition
  4. Dcondensation

Answer: B. evaporation

Explanation

The correct answer isevaporation . Key Points Change of a liquid into gas at any temperature below its boiling point is called evaporation. Evaporation is the process by which water changes from a liquid to a gas or vapor . Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Additional Information Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. An example of sublimation is naphthalene, dry ice. Condensation is the process by which water vapor in the air is changed into liquid water . Condensation is crucial to the water cycle because it is responsible for the formation of clouds. Condensation is the opposite of evaporation. Crystallisation is an example of physical change . It involves separation of solid-liquid separation technique, which involves the transfer of solute to the pure solid crystalline phase from the liquid solution.
