    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.
