Thermometer mercury into the foot inside will not die 20

Generally not, mercury is indeed poisonous, but the amount is not large, and it generally causes a lot of cell death in the body.

It is recommended that you see a doctor and see what the doctor says.

Wishing you all good health.

It's okay, of course it will cause a little harm to the blood, mercury, which is mercury, is just a little contact with the capillaries, so there is no need to worry.

Let's see a doctor. Mercury is poisonous. It's not an option.

The thermometer can't see the mercury line because it wasn't reading correctly or wasn't measured in the right way.

1. The reading method is incorrect.

The correct way is to hold the tail of the thermometer in one hand, that is, away from the end of the mercury column, so that the eye and the thermometer are at the same level, and then slowly turn the thermometer, and when you see a very thick mercury column from the front, you can read the corresponding temperature value. Be careful not to touch the mercury end of the thermometer with your hands, as this will affect the mercury column and cause the value to be inaccurate.

2. The measurement method is incorrect.

Before use, make sure that the power of the thermometer is below 35, if it is not below 35, you can use your hand to hold the upper part of the thermometer and throw it down. The armpit measurement takes 5 to 10 minutes, and the end of the mercury bubble is close to **, and if the time is too short, it will affect the accuracy of the body temperature, which may cause the mercury line not to rise and the line cannot be seen.

Precautions for mercury thermometers:

1. Verify the thermometer to make sure that the thermometer can be used normally.

2. When you take it out before the time is up or accidentally move it, you need to re-measure and recalculate the time.

3. Before taking your body temperature, do not eat foods (hot water, cold drinks, etc.) that will affect the measurement results.

4. Before measuring body temperature, do not do strenuous exercise or take a bath and other behaviors that affect the measurement results. If you drink hot drinks, exercise vigorously, are agitated, and take a bath, wait 30 minutes before taking the test.

5. The maximum temperature of the mercury thermometer is 42 degrees Celsius, so the temperature should not exceed 42 degrees Celsius when storing or cleaning, and the thermometer should not be put into hot water for cleaning or measuring the temperature of other objects.

Possible. To determine whether the mercury thermometer is damaged or malfunctioning, use the observation number method. The easiest way is to observe the readings on the thermometer and use the thermometer to measure the temperature of different objects, if you find that the temperature value has not changed, it means that the thermometer is damaged and malfunctioning.

Mercury thermometers can also sometimes have common malfunctions. <

Possible. To determine whether the mercury thermometer is damaged or malfunctioning, you can use the observational numerical method. The easiest and most straightforward way is to observe the readings on the thermometer and use the thermometer to measure the temperature of different objects.

Mercury thermometers sometimes have common failures, if the tip of the mercury thermometer is damaged or there is a leak of steam during the production process, it will cause the liquid mercury to rise normally or can not return to the top of the electronic thermometer, which will immediately cause the accurate measurement data information is inaccurate or there is a significant deviation. In addition, mercury thermometers are sensitive and can be easily damaged after bumps.

Mercury can accumulate in living organisms and is easily absorbed by the respiratory and digestive tracts. Minamata disease is a type of mercury poisoning. Mercury damages the central nervous system and has adverse effects on the mouth, mucous membranes and teeth.

Prolonged exposure to high mercury can lead to brain damage and death.

Melting point, boiling point, density. The cohesion is very strong, stable in the air, and mercury vapor evaporates at room temperature, and the vapor is highly toxic. Natural mercury is a mixture of seven isotopes of mercury.

Mercury is slightly soluble in water and increases in solubility in the presence of air. Mercury is ubiquitous in nature, and general animals and plants contain trace amounts of mercury, so there are trace amounts of mercury in our food, which can be metabolized through excretion, hair, etc.

Main features of mercury migration and transformation:

1) Mercury is the only heavy metal that can complete the cycle in the ecosystem. Once mercury is discharged into the water, it passes through the food chain and the concentration of methylmercury in fish contaminated with mercury can be up to 10,000 times higher than in the water.

2) The mercury cycle shows that complex processes include: migration of particulate matter; sedimentation of wet and dry materials; volcanoes volatilize into the atmosphere; sedimentation into the sludge; Methylmercury is formed in response to bacteria; entry into the organism; Accumulation in living organisms.

3) Biomethylation: Under the action of microorganisms, inorganic mercury such as metal mercury and divalent ionic mercury will be converted into methylmercury and dimethylmercury, which is called mercury biomethylation.

Mercury is a heavy metal, which can cause heavy metal poisoning, mercury enters your kidneys with digestion, and your life is over (Lu Junyi on the Water Margin died like this), when doing experiments, the body that comes into contact with mercury cannot have wounds.

The one with the liquid in the thermometer refers to the mercury thermometer, and the liquid inside is mercury.

Mercury, also known as mercury, is the only metal in liquid form at room temperature and pressure, and the liquid substance with a silvery-white metallic luster in the thermometer is mercury. An ordinary stick glass thermometer contains about 1 gram of mercury, and a desktop sphygmomanometer contains about 50 grams of mercury.

And at room temperature, it can evaporate. Mercury vapor and mercury compounds are highly toxic. When the mercury thermometer is broken, the mercury evaporates into a gaseous state and is easily inhaled into the respiratory tract.

Silver is the only metal in a liquid state at room temperature, and once the supplies containing it are broken, the mercury will soon evaporate and form a sphere to roll down. Wear gloves and collect the mercury as soon as possible.

The method of collection is to use a small cotton swab or tape paper to collect the mercury spilled on the ground, put it into a small bottle that can be sealed, such as a plastic bottle such as a beverage bottle, and add a small amount of water to the bottle, and write "waste mercury" and other identifying words on the bottle, and hand it over to the waste liquid management personnel of the community neighborhood committee for disposal or send it to the environmental protection department for special treatment.

The thermal expansion and contraction characteristics of mercury were used to measure the temperature of vertical hail. Although many liquids have the characteristics of thermal expansion and contraction, the temperature sensitivity of mercury is higher than that of ordinary liquids, because it is a liquid metal at room temperature, so it has the characteristics of a metal that is highly sensitive to temperature.

The pipe diameter connected between the head of the thermometer and the temperature indication area is smaller than the pipe diameter of the indication area, so after the thermometer is taken out from the temperature measurement place, because the temperature drops suddenly, the volume of mercury in the head suddenly decreases, and because the connecting part of the pipe is small, the mercury in the indication area does not have time to return to the head, so as to remain in the indication area, which is convenient for reading the body temperature.

Why do you have to shake it out a few times before your next measurement? It is to reconnect the mercury in the indication area with the mercury at the head, and to remove the small diameter of the small pipe to make a wide partition.

Therefore, you can't make a thermometer with other liquids, you can only make an ordinary thermometer.

Hello coarse, mercury thermometers are more accurate in measurement, so thermometers use mercury more.

The general gas such as the hood temperature gauge is not used, and the cost is low.

No, a mercury thermometer is a type of expansion thermometer. It is sealed with glass, and the temperature is measured by the principle of Xunkai thermal expansion and cold contraction, and the structure is simple and not easy to break. However, be careful not to use it beyond the range and not break it.

How to use:1. Calibration should be carried out before use (the standard liquid temperature multi-branch comparison method can be used for calibration or the thermometer with higher accuracy can be used for calibration).

2. It is not allowed to use the measured value with a temperature exceeding the maximum scale value of the thermometer.

3. The thermometer has thermal inertia, and it should be read after the thermometer reaches a stable state. Readings should be taken in the highest tangent of the temperature convex meniscus with a direct gaze. Mu early call.

4. The mercury thermometer should be perpendicular to the flow direction of the measured working fluid or inclined.

How can it break?

Mercury thermometer is a kind of expansion thermometer, the freezing point of mercury is: -39, the boiling point is: , used to measure the temperature within the range of 0--150 or 500, it can only be used as a local supervision instrument.

You look at the measurement range of your mercury thermometer and you'll find out.

The normal temperature of the human body is 37, and the question of a person with a high fever may reach 41, so 42 is worried about the failure of the mercury thermometer, and you are a little worried.

At most, if the mercury column is too high to return to its original position, or if the mercury column is broken, it can be reset by the following methods:

1) Cold repair method: insert the thermometer temperature package into the dry ice and alcohol mixture (the temperature shall not exceed -38) for cold shrinkage, so that all the mercury in the capillary tube shrinks to the temperature measuring bag.

2) Thermal repair method: slowly insert the thermometer into the thermostatic bath with a temperature slightly higher than the upper limit of the measurement, connect the broken part of the mercury with the entire mercury column, and then slowly take out the thermometer and gradually cool it to room temperature in the air.

Disinfection with alcohol is for hygiene, and it has nothing to do with whether it is bad or not.
