When do you see clouds?
Fog is caused by a drop of temperature when the air is moist. Air always has some moisture in it. On a warm day there will be quite a lot of moisture in the air caused by evaporation of surface water or transpiration from plants. However, if the temperature drops the moisture starts to condense into droplets big enough to cause light scatter. We call this size water droplets low to the ground - fog. Early morning fog often clears as the sun hits it due to the re-evaporation of the water.
Is dense fog opaque transparent or translucent?
In general, it depends. Most of the time, it is translucent because you can only see unclear images through the fog. Other times, if you can't see anything through the fog, then it is opaque, not translucent.
Why doesn't the window fog up when you breathe on it on hot days?
It's because on a hot day, the window is not cold enough to condense the water in the breath that is breathed on it. The solubility of a liquid in a gas is temperature dependent, so the water in breath which is a gas mixture saturated with moisture precipitates out when it hits a cold pane of glass. Similarly when you open an oven the moisture from the food cooking lets a steam escape that will fog up your glasses.
What are some types of condensation?
Some types of condensation include dew, which forms on surfaces when warm, moist air cools at night; fog, which occurs when water vapor condenses in the air near the ground; and clouds, which form when air rises, cools, and loses its capacity to hold moisture. Another type is frost, which develops when water vapor directly transitions from gas to solid on cold surfaces, often in freezing temperatures. Each type reflects the cooling of air and the presence of moisture.
Why would a window or mirror be covered in moisture?
A window or mirror may be covered in moisture due to condensation, which occurs when warm, humid air comes into contact with a cooler surface. This temperature difference causes the water vapor in the air to cool and condense into tiny droplets, resulting in moisture on the surface. Factors such as high indoor humidity, temperature fluctuations, or poor ventilation can contribute to this phenomenon. Additionally, it is more common in colder weather when indoor heating creates warm air inside while the glass remains cold from the outside temperature.
What is the mechanism that creates fog in a fog machine?
A fog machine creates fog by heating a special fog fluid, which turns into vapor when it comes into contact with the cooler air outside the machine. This process creates a misty effect that resembles natural fog.
How does fog form over land?
Fog forms over land when the air near the surface cools to the point where it can no longer hold all the moisture it contains. This causes the moisture in the air to condense into small water droplets, creating fog. Factors such as temperature, humidity, and wind conditions play a role in fog formation.
How do you use the word moisture in a sentence?
The moisture in the air caused the windows to fog up.
Does cold air or warm air make fog appear faster?
Warm air makes fog appear faster, as the warm air can hold more moisture than cold air. When warm, moist air comes into contact with cooler air, it cools and can no longer hold all the moisture, leading to the formation of fog.
Fog droplets remain suspended in the air because the what?
Fog droplets remain suspended in the air because the air is saturated with moisture, creating a condition where the droplets do not evaporate easily. This saturation of moisture allows the droplets to stay suspended and form the fog that we see.
Why did the people of Chungungo need to use to catch moisture in the air?
to catch the fog
When moisture in tha air on a rainless day is called?
When there is moisture in the air on a rainless day, it is often referred to as humidity. This moisture can make the air feel more heavy or sticky.
Fog is percepitation?
Fog is precipitation in cool air with a moisture laden mass. The moisture condenses, making air heavier. It begins to become visible air, or fog, nearest the surface of water or ground. This starts anywhere from sundown to sunup. With sunup, sunlight starts to warm the air. The condensation lowers; the density lowers. With lower density, the visible fog begins to rise. The fog wisps return to the sky to be a normal cloud.
What do we call the dirty haze that forms when air polution combines with moisture in the air?
Smog -- smoke and fog
What is moisture-laden air?
Humidity
How can it be foggy when it's cold?
The general answer is that fog is caused by condensation of water in the atmosphere. It's like a cloud, except that the cloud is in contact with the ground. That's what fog is. Air has moisture in it, and the amount varies. Also, the amount of moisture that air can hold varies as a function of temperature. The warmer it is, the more moisture that air can hold. But if it cools off, air can't hold as much. Fog forms when the temperature drops to the point where the air cannot hold all the moisture in it at that temperature. This at 100% relative humidity, which is called the dew point. Fog begins to form as air, which had previously been warmer and had moisture in it, cools until it reaches the dew point. Then we'll see tiny droplets of water forming in the air close to the ground, which is fog. A link can be found below.
How does a ground fog come about?
Water vapor in the air condenses when the ground cools at night. the cooler ground (often due to radiation into space when it is clear) cools the air near the ground. This cooler air cannot hold as much moisture as warm air and the moisture condenses as fog.
