How to judge when the water temperature is around 80 degrees

Judge by tactile method, observation method, etc.

1. If you touch the side of the cup with your fingers and it is hot, the water temperature is close to 80 degrees.

2. Observe the color and bubbles of the water. When the water temperature approaches 80 degrees, the water becomes cloudy and produces a large number of bubbles.

With non-standard atmospheric pressure, the boiling point of water is 80 degrees. Can boiled water be drunk?

It cannot reach 100 degrees because the air pressure is relatively low.

It takes a while to boil at 80 degrees, about 15 minutes. Most bacteria can be killed, but there. There will always be heat resistant bacteria. In fact, even if it's 100 degrees, it won't kill all the bacteria.

But don't worry too much about whether the water is safe to drink, because most pathogenic microorganisms ppresent in the water will be killed when it is heated to 80 degrees. As for whether you want to know more about the sterilization temperature of different microorganisms, it is a very complicated topic. For example, you can refer to books on microbiology and food hygiene.

How to check water temperature. it's 80 degrees

Of course not. Even if the air pressure is there and you see that the water is boiling, the water at 80°C is still only 80°C and the toxic substances cannot be discharged.

Under normal circumstances, we boil water and drink tap water, which usually comes from a nearby river or lake. Think about it, the lake water is so dirty. Let's take the example of the area near my house. Anyway, I've always heard about the river near our house since I was a child. Sewage, domestic wastewater andhe food waste in our region is all dumped into this river. When I first heard about it, I was disgusted. I didn't want to touch the tap water in our house at all. When I brushed my teeth, I simply poured water from the water dispenser. Later, when I grew up and gained some intelligence, I realized that it had to be purified before being thrown back into the river. I was young and ignorant, haha. But even though I thought about it and thought about it, it still feels dirty. We have restaurants on boats on the river here, and I have also heard of people defecating in the river. These are not processed. Therefore, before the tap water reaches each of our homes, it will be disinfected again at the water plant, this time with chlorine. The unique smell we smell in tap water is actually chlorine.

The greatest danger of chlorinated water is that it containsnt halogenated hydrocarbons and chloroform. Both of these substances can cause cancer. Therefore, when we boil water for drinking, let us not drink it as soon as it is boiled. It is best to let the water reach 100℃ then boil it for 3 minutes to let these toxic substances evaporate with the water vapor. So if we drink more water, we will become beautiful.

Of course, if you are in a place where water is scarce, let alone boiling, many people may drink raw water. It may not seem like a big deal at the time, but it is very harmful. for the body in the long term, maybe there are parasites in the water, then they grow in your stomach and turn into long strips. It's disgusting to think about. However, special treatment is given in special circumstances. Just be more careful when conditions improve in the future.

Can you drink 80 degree water directly?

How to check if the water temperature is 80 degrees:

Materials: A digital thermometer.

1. First we need to boil the water in a saucepan.

2. After the water is boiled, we bring the water into the cup and let it cool for a while.

3. After that, we can put the digital thermometer into the cup to measure the water temperature. We can also put the digital thermometer into water after boiling it. we can tell you if the water temperature is 80 degrees.

You can drink it, but if conditions permit, it is best to reach 100°C before drinking it.

On the plateau, due to limited conditions, water is often boiled below 100°C because the boiling point of the water will be lower on the plateau. The inhabitants of the plateau also used thise incompletely boiled water. We therefore see that water at 80 degrees can be drunk directly. However, in daily life, it is not recommended to drink water at 80 degrees. It is best to boil it completely at 100°C.

Water (chemical formula: H?O) is an inorganic substance composed of hydrogen and oxygen and is not toxic. It is a colorless and odorless transparent liquid at normal temperature and pressure, known as the source of human life. Water includes natural water (rivers, lakes, atmospheric water, sea water, groundwater, etc.) {containing impurities}, distilled water is pure water, and artificial water (water obtained by combining hydrogen and oxygen atoms through chemical reactions). Water is one of the most common substances on earth. It is an important resource for the survival of all life, including inorganics and humans. It is also the most important component of oliving organisms. Water has played an important role in the evolution of life. It is a non-renewable resource in the narrow sense and a renewable resource in the broad sense.
