Q:

What is the opposite of vaporization?

A:

Quick Answer

The opposite of vaporization is called condensation. Vaporization is a change of state in which a substance goes from liquid to gas, while condensation is when a substance goes from gas to liquid.

Substances can change states due to changes in temperature or pressure. Typically, substances change from one level of energy to the next closest one, such as from water to gas.

However, there are some exceptions that skip the middle energy state. For example, sublimation (solid to gas) usually occurs when dry ice is exposed to room temperature air. Changes in state are driven by changes in average molecular energy.

Gases have the most energy, while liquids are in the middle and solids have the least.

  • Q:

    What is the difference between condensation and evaporation?

    A:

    Evaporation happens when liquid turns into gas whereas condensation occurs when gas changes to liquid. The higher the temperature of the liquid, the higher the rate of evaporation becomes. In contrast, the condensation rate rises when the temperature of gas lowers.

  • Q:

    How does gas become a liquid?

    A:

    The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the water cycle. Because pressure varies inversely with temperature, as temperature decreases, pressure goes up, causing the gas molecules to move with progressively less kinetic energy. Eventually, liquid vapor and droplets form, and the gas begins to condense.

  • Q:

    Why do water droplets form on the outside of a glass of ice water?

    A:

    Water droplets form on the outside of a glass of ice water due to condensation. The temperature of the glass is cold enough to cool down the water vapor in the surrounding air, so it turns from gas to liquid. Therefore, drops form more readily during warm weather than cold weather.

  • Q:

    What is the process of condensation?

    A:

    The process of condensation occurs when molecules of gas lose thermal energy which causes them to change into a liquid state. Condensation is a change in the physical state of matter and the process is the opposite of evaporation. The word condensation frequently refers to the water cycle, defining the change of state that occurs when water vapor condenses into a liquid after coming into contact with a colder surface or environment.
