Mercury broken in a thermometer in the bedroom can be completely volatile for a few hours

Mercury can be volatilized indoors within 72 hours if the windows are opened for ventilation.

Mercury is the common name of mercury, the chemical symbol is Hg, the 80th position of the periodic table, is a dense, silvery-white, liquid transition metal at room temperature, and is a D-block element. It is often used to make thermometers. The freezing point of mercury is °C, the boiling point is °C, and mercury has the smallest range of liquid temperature among all the metal elements.

Mercury is chemically stable and insoluble in acids or alkalis. Mercury can evaporate at room temperature, and mercury vapor and mercury compounds are often highly toxic (chronic).

Widely used thermometers, blood pressure monitors and other equipment have caused mercury easy to pollute indoor and other environmental problems, break the mercury thermometer indoors, do not panic, you can immediately see the naked eye of the broken mercury beads with a piece of paper (because the cohesion of mercury is very large, with a cotton swab can not pick up mercury, this is extremely unscientific, irresponsible statement) hold up and put into a sealed water bottle, if there are small mercury beads can be pushed together with a piece of paper, mercury will automatically gather into a small ball, and then collect.

To be on the safe side, nitric acid can be used to wipe mercury-contaminated floors to completely eliminate mercury contamination in the presence of some simple chemicals. However, it is absolutely not possible to cover the method with sulfur powder, because it is difficult for mercury to be combined with sulfide at room temperature, and mercury pollution cannot be removed. In order to completely remove mercury contamination, the chamber can be fumigated several times by means of iodine vapor fumigation until the cuprous iodide test paper does not change color.

Experiments have proved that mercury leakage on a daily basis can be glued and collected with scotch tape commonly used in the household, which is better than that of paper pieces, and mercury leakage from thermometers and sphygmomanometers can be treated in this way.

It will disappear within a day, and even if there is a residue, it will be fine, because there is very little mercury in it, and it will be fine if it is ventilated.

The mercury in the thermometer shattered and took about 10 hours to evaporate.

Under normal circumstances, if the thermometer is broken, it is necessary to pay attention to the circulation of air in the room, open doors and windows, and keep away from mercury to prevent the vapor of mercury from being inhaled by the human body and causing poisoning.

The working substance of the thermometer is mercury. Its glass bubble volume is much larger than that of the thin tube above. Due to the influence of body temperature, the mercury in the bubble produces slight changes, and the expansion of the volume of mercury makes the length of the water in the tube change significantly.

The change of the body temperature is between 35 and 42, so the scale of the thermometer is 35 to 42, and the range of each degree is divided into 10 parts, so the thermometer can be accurate to 1 10 degrees.

The moment the thermometer shattered, it began to evaporate.

Open windows for ventilation, wear gloves and be careful not to expose your metal watches, rings, etc. to mercury.

If the amount is large, you can scrape it directly into a bottle with a piece of cardboard or something, collect the small place with tape, and then wipe it with moistened paper, and put the processed thing in a bottle, which is best covered with water to avoid volatilization.

When you go out, the window is open, mercury accumulation poisoning, if you really feel unwell recently, you can go to the hospital to check the blood mercury.

The thermometer breaks the mercury and can be volatilized in 2-3 months.

If the mercury thermometer is accidentally broken, the mercury inside the glass will flow out, and the mercury can volatilize at room temperature to form mercury vapor.

Mercury thermometer:

A mercury thermometer, a type of thermometer, is made of glass with a column of mercury that rises with body temperature. Mercury thermometers are widely used in the medical field and in ordinary households, and mercury thermometers are available in some pharmacies.

The first thermometer was invented by Galileo in the 16th century. But it wasn't until 300 years later that an easy-to-use, reliable thermometer was designed. Mercury is stored inside the mercury ball at the end. When mercury is heated, it expands, rising along a very narrow glass tube.

Therefore, a small change in body temperature can cause a large increase in mercury in the glass tube. After taking your temperature, shake the thermometer vigorously to return the mercury to the ball.

In 1714, Gabriel Wallenheitt developed a mercury thermometer that set a scale within the freezing point of water and the range of human body temperature. A Dutch doctor used it to take the temperature of a patient with a fever, but the thermometer was still too large and most doctors failed to use it anytime soon.

In 1868, the German professor Wendelich published Disease and Body Temperature, in which he recorded the changes in the body temperature of 10,000 patients, and the thermometer he used was twice the size of the Albert thermometer, which took 20 minutes to record the temperature at a time.

Later, in 1867, Albert designed a thermometer that could quickly and accurately measure body temperature and was only about 15 centimeters long. Unfortunately, Albert's thermometer came out too late to help Carl Wendellicht.

Around 1980, the talking thermometer was invented. The membrane liquid crystal temperature orange mask meter is green when the body temperature is normal, yellow for low-grade fever, and red for high-level fever. In 1988, an electronic respiratory pulse thermometer appeared, which allowed telemetry.

No, when the head of the mercury thermometer (or thermometer) is damaged, the mercury inside will spill, but the mercury will volatilize when the temperature is high, so you don't have to worry about opening the window for ventilation. Mercury is toxic, and after leakage, try to avoid contact with it, reduce the inhalation of steam, and never enter it.

Mercury is the only metal that is liquid at room temperature, and when the products containing it are broken, the mercury evaporates. Moreover, it has particularly good adsorption. Mercury vapor is easily adsorbed by walls and clothing, and becomes a source of continuous air pollution.

Although it will not cause much harm to the body if inhaled in small amounts, it can cause mercury poisoning if inhaled in large amounts for a long time.
