Question: The process of removing gas from air is called: ((MCAER 2014))
Options:
Absorbs heat from the surroundings
Releases heat to the surroundings
Does not involve heat exchange
Is a chemical reaction
✅Explanation: Evaporation is a process that requires energy to break the intermolecular forces holding the liquid together. This energy is absorbed from the surroundings, resulting in a cooling effect.
🔑Key Points:
-Evaporation
-The process by which a liquid changes into vapour even below its boiling point is called evaporation.
-It may occur even at room temperature.
-Evaporation causes cooling because when a liquid evaporates, it draws the latent heat of vaporisation from the surface it touches.
