The correct answer is option 1 - Vaporization.
Condensation is the process in which water vapor changes into liquid water. It occurs when the temperature of the air decreases and the air becomes saturated with water vapor. This can happen when warm air cools down, as in the case of clouds or fog.
Vaporization, on the other hand, is the process in which liquid water is converted into water vapor. This occurs through boiling or evaporation, where the heat causes the liquid molecules to gain enough energy to break free and become gas.
Therefore, condensation is the opposite of vaporization. While condensation involves the formation of liquid water from water vapor, vaporization involves the conversion of liquid water into water vapor.
