False
Water vapor is already a gas since it is the gaseous form of water. If you are referring to how water vapor turns into liquid water, it does so through condensation when the temperature decreases enough for the vapor to condense back into liquid form.
In order for clouds to form, water vapor needs a surface to condense upon. This can be provided by tiny dust particles, salt particles, or other aerosols present in the atmosphere. These particles serve as nuclei around which water vapor can condense to form cloud droplets.
Water in the atmosphere exists in a gaseous state, known as water vapor. Depending on temperature and pressure, water vapor can condense to form liquid droplets (clouds) or solid ice crystals (snowflakes, hail) in the atmosphere.
condense
If the relative humidity reaches 100%, the air is holding the maximum amount of water vapor it can at that temperature. Any additional water vapor will condense into liquid water, such as forming dew on surfaces or creating clouds and precipitation.
True. Water vapor can condense directly into liquid water without needing a solid object as a surface for condensation to occur. The process of condensation can happen in the air when water vapor cools and reaches saturation point.
Not necessarily. Water vapor can condense into liquid water on tiny particles in the air, such as dust or aerosols, called condensation nuclei. However, having a solid surface for condensation, like a glass, can accelerate the process.
Particles are needed because then the water vapor can condense on them
True
Actually, the temperature at which water vapor begins to condense into liquid water is called the dew point. It is the temperature at which air becomes saturated with moisture.
Water vapor must be present in the air, along with cooling temperatures or rising air currents, for the vapor to condense and form clouds. Condensation nuclei, such as dust or pollutants, also aid in cloud formation by providing surfaces for water vapor to gather and form droplets.
False, Dew Point is where water vapour begins to condense into a liquid
True. The dew point is the temperature at which air reaches saturation and water vapor in the air begins to condense into liquid water on surfaces.
The most obvious answer is that the vapor will condense rapidly, even possibly before your eyes. By condense, I mean that the vapor will quickly turn into a liquid state. It will then freeze into a solid state (ice).
This can be called various things: condensation, fogging, beading up.
Solid particles of dust serve as nuclei around which water vapor can condense to form cloud droplets. Without these particles, water vapor would have a harder time condensing and forming clouds. Dust particles also provide a surface for water vapor to adhere to, initiating the cloud formation process.
