What is the temperature of boiling water in Chongqing?

What is the temperature of boiling water in Chongqing?

100 degrees Celsius

What is the boiling point of boiling water in Chongqing?

When water is at one atmospheric pressure The boiling point is 100°C. When the atmospheric pressure changes, the boiling point changes in the opposite direction

Chongqing cold water temperature

The normal cold water temperature in Chongqing is generally around 30 degrees. . .

Chongqing is one of the three hot stove cities. In the hot summer days, if no other measures are taken, the normal indoor cold water temperature is around 28 degrees.

If you use outdoor sunlight, it can reach 35-45 degrees.

Is the boiling point of water in Chongqing correct? 98 degrees Celsius?

The temperature when water boils is called the boiling point of water. We usually say "the boiling point of water is 100°C", which refers to the temperature when water boils under one atmospheric pressure (standard atmospheric pressure). So the boiling point of water Is it constant? No. The boiling point of water changes with changes in atmospheric pressure: as the air pressure increases, the boiling point rises. Because the atmospheric pressure on the water surface always prevents water molecules from evaporating, the air pressure rises. When it is high, water must have a higher temperature to turn into water vapor. Generally, on the ground at a low altitude, the atmospheric pressure is basically one atmosphere. In places below sea level (such as very deep mines), the air pressure is higher than one atmosphere. Atmospheric pressure, when water is boiled there, the boiling point of water will increase. According to measurements, when the depth increases by one kilometer, the boiling point of water will increase by 3 degrees.

On the contrary, as the air pressure decreases, the boiling point also decreases. For example, the higher the altitude, the thinner the air and the lower the air pressure, the boiling point of water in this place decreases. On Mount Everest, the top of the world When boiling water, as long as it reaches 73.5℃, the water will be "boiled".

So because of Chongqing’s altitude and pressure, the boiling point of water is 98°C.

The temperature in Chongqing is high It's 30 degrees, so hot. How to prevent heatstroke?

There is no need to wear warm clothing.

33℃ - Sweat glands start to activate. When working at this temperature for 2 to 3 hours, the "human body" air conditioner - sweat glands start to activate, dissipating the accumulated body temperature through slight sweating.

35℃ - The heat dissipation mechanism reacts immediately. At this time, the superficial veins dilate, the skin sweats slightly, the heart beats faster, and the blood circulation accelerates. For some elderly, frail and poor heat dissipation patients, local cooling is required. This temperature is also the starting temperature for activating indoor air conditioning.

36℃——The human body "self-cools", the first level alarm temperature. At this temperature, the human body will dissipate heat through evaporation of sweat and "self-cool". At this time, you must pay attention to supplementing drinks containing salt, vitamins and minerals to prevent electrolyte disorders, and other cooling measures should also be taken.

38℃——Multiple organs participate in cooling, second level alarm temperature. Once the temperature rises to 38°C, it is difficult for the human body's sweat glands to maintain normal body temperature. Not only does the lungs "gasp" rapidly to exhale heat, but the heart also speeds up, outputting 60% more blood than usual to the body surface to dissipate heat. At this time, cooling measures, cardiac drug care and treatment cannot be relaxed at all.

39℃——Sweat glands are on the verge of failure, level three alarm temperature. The sweat glands are exhausted from their work and are incapable of doing anything and tend to fail. At this time, there is a high risk of a heart attack.

40°C - the brain is focused on one thing and not the other, a level four alarm temperature. The high temperature has reached the vital center, making people dizzy and unsteady. At this time, people must move to a cool place or use an air conditioner to cool down.

Salt boiled water

Traditional Chinese medicine calls boiled water the "king of a hundred medicines". When drinking boiled water, you should choose fresh cool boiled water (20°C to 25°C) that is naturally cooled after boiling. This kind of boiled water has specific biological activity and can easily enter the cells through the cell membrane and be quickly absorbed and utilized. It is best to add some salt when drinking boiled water. High temperatures in summer lead to excessive sweating and reduced salt content in the body. The osmotic pressure in the body will lose stability, leading to heatstroke. Drinking more salted water or salted tea can replenish the salt lost in the body, thus achieving the effect of preventing heatstroke.

Tea

Potassium is an important trace element in the human body. Potassium can maintain the normal function of nerves and muscles, especially the normal movement of the myocardium. Scientific analysis shows that tea contains more potassium, accounting for about 1.5% of its total potassium content. Potassium is easily excreted with sweat, so tea with a suitable temperature should be the first choice drink in summer.

In summer, the sun is scorching and the heat is scorching. You sweat a lot and feel thirsty. Drinking more hot tea is the best way to prevent heatstroke and cool down. The benefits of drinking hot tea are:

1. It can refresh your mind and eliminate fatigue.

2. It can produce fluid and quench thirst. Drinking hot tea can stimulate the oral mucosa and promote... >>

Is there a big difference in temperature between the water and air in the pond in Chongqing in winter?

In Chongqing in winter The temperature of the water in the pond is not much different from that of the air.

The average temperature of the coldest month in winter in Chongqing is 4-8°C. At this average temperature, the temperature of the water in the pond and the air are not much different. If you encounter extreme weather, such as one that is close to the lowest value for the same period in history. to -8°C or even lower. Since the water temperature will not drop below zero, there will be a difference of about 10°C from the air temperature. At this time, the temperature difference between the water and the air in the pond is large.

Because the specific heat capacity of water is large, the water temperature is relatively stable; while the specific heat capacity of air is small, the temperature changes greatly. Therefore, in natural environments, the air temperature is often higher than the water temperature in summer, while the air temperature is lower than the water temperature in winter. In a long-term stable environment, even if the water vapor temperature is different at the beginning, the two temperatures will tend to be consistent in the end. Therefore, generally in winter, when the temperature is above zero, the temperature of the water in the pond and the air are not much different. After the temperature drops below zero, As temperatures drop, the difference in temperature between the water and air in the pond gradually increases due to the ice blocking it.
