Why does dust accumulate on the table even if the window is not opened?

Because dust does not exist in the air all the time, in fact, we can't see it with the naked eye, but fine particles will also float, and after a long time, even if you don't open the window, a lot of dust will accumulate on the table, which is normal.

Even if you don't open the window, there will be some dust floating in the air, so it will fall on the car, so some dust will accumulate on the table.

Because it is not used for a long time, the dust floating in the air will fall, so there will be a lot of dust on the table.

There will also be a certain amount of dust in the air, as long as the air circulates there will be dust, unless your home is in a vacuum state, otherwise there will be a certain amount of dust after a long time.

You must know that dust is everywhere, it is not that if you close the window, the dust will not come in, and dust will fall on the table all the time, but because it is used regularly, it will not accumulate dust.

It's because there's a lot of dust on your walls, and when that dust falls, it sticks to your desk.

Yes, because the air itself is filled with smaller particles, which accumulate over time as it settles slowly.

I think it's because there will be dust in the room, so the dust in the room will slowly fall on the table, and the table will be full of dust.

Because there is dust on the floor, and at the same time, there is a lot of dust on people's bodies that will be brought into the house, and dust will naturally accumulate.

Because there are a lot of dust floating in the air, it is impossible to be free of dust.

I think even if you don't open the windows, the city will be taboo on the table, because there is a lot of dust in the air, and there is no way to do it.

Even if the windows are closed indoors and no outside dust comes in, after a period of time, the dust contained in the air will still slowly settle down and accumulate on the desktop. This will allow dust to accumulate on the table.

Have you ever had the experience of going out for a trip or a business trip for a period of time, closing the doors and windows well when you left, and still a lot of dust fell on the table when you came back, why is this?

This is a natural effect, such as wind erosion and ocean tides, human activities, as large as industrial production and as small as the ** detritus shed off everyone's body, all the time to disperse all kinds of small particles that are invisible to the naked eye into the atmosphere, of which the larger particles will settle quickly under the action of gravity, and the smaller particles can be suspended in the air for a longer time.

Turn on a well-directed flashlight or laser pointer in a dark room and you'll see a pillar of light in what should be an empty room, caused by the light refracting on airborne particles.

In this way, even if the window is closed, no outside dust will come in, and after a period of time, the dust contained in the air will still slowly settle down and accumulate on the table. In the pharmaceutical, microelectronics and other production industries, even these tiny dust suspended in the air can cause serious damage to the product, so it is necessary to adopt strict air purification measures to improve the quality of production by filtering dust-free air in the production workshop.

There is dust in the composition of the air, and as long as there are people in the house, the clothes they wear will also drop dust as they put on, take off, and move. Indoor ones are mostly produced from the air, and there are also soft quilts that are produced.

The movement of family members, the air and dust are constantly moving, driving the floating of dust, and the rise of heat driving dust, relativity one, may be the cause of geothermal heat.

The house itself is unclean, and there is dust in the composition of the air, and as long as there are people in the house, the clothes they wear also shed dust when they put on, take off, and move.

1: Dust in the composition of the air 2: Dust brought back from the outside 3: The uncleanliness of the house itself 4: Furniture needs to be cleaned frequently.

Ash is not transmitted from the outside world, but is mostly produced indoors from the air, and soft quilts are also produced.

There are several kinds of dust, one is the dust in the outside air, one is the line dust in the clothes and curtains in the room, and the other is the dust that naturally peels off the walls in the room. It can be seen that if you don't open the window, it is not necessarily free of dust, because the dust source is in the room.

Dust researchers in the United States estimate that 43 million tons of dust fall from the skies over the United States each year, of which 31 million tons come from nature and the remaining 12 million tons are man-made. The most common form of dust is earth, followed by salt, where small crystals of salt fly out of the ocean at a rate of 300 million tonnes per year, and once swept into the sky, they travel around until they land on a ball of dust. The dust drifts higher up in the sky, where it becomes the core of the formation of water droplets.

If there is no dust, there are no clouds. Some dust is produced by volcanic activity, forest fires. Dust also comes from outer space, with comets and disintegrating meteorites adding 10,000 tons of weight to the Earth every year.

Amazingly, there's always more dust indoors than outside. In terms of particles that can enter the respiratory tract, the amount of dust in indoor air is twice as high as in outdoor air. You won't believe what's living in the dust ball beneath your bed – for example, there are 42,000 dust mites per ounce of dust that feed on the 50 million** scales that we shed every day, so opening the windows makes the room cleaner.
