1 kilowatt hour of electricity is equivalent to 1 kilowatt hour, i.e.
W=Pt=1000x3600=3600000 Joules
Electricity production is the conversion of the potential energy of water in< /p>
EP =mgh
3600000=mx10x10
m=36000 kilograms. But there is no consumption when mechanical energy is converted into electrical energy. The efficiency of converting water energy into electrical energy is about 70%
So, 36,000/0.7 = 51,428 kilograms.
The highest water temperature is 100 degrees. How many degrees coldest can it be?
Under normal circumstances, in our lives, the maximum temperature of water can reach 100 degrees, regardless of the temperature, the water boils and turns into water vapor. The water is at 0 degrees, when the temperature is below 0 degrees, the water solidifies and turns into ice. These are all in our lives, that is, the highest temperatures et the lowest of water under standard atmospheric pressure.
However, under certain special circumstances, the water temperature will still increase and it will not vaporize or freeze. The boiling point of water is normally 100 degrees, but this boiling point will increase as the pressure increases. When the pressure reaches 225 atmospheres, the boiling point of water is 374 degrees. This temperature is called critical temperature. If the pressure is higher, the water vaporizes.
Sometimes the maximum temperature of water in normal life does not reach 100 degrees, that is, the boiling point is below 100 degrees. For what ? This is because the boiling point of water changes with the change in altitude. Generally speaking, when the altitude is 0 meters, the boiling point of water is 100 degrees. At an altitude of 1,500 meters, the boiling point of water is 95 degrees. To altitude of 2,000 meters, the boiling point of water is 95 degrees, the water temperature is 93 degrees, at an altitude of 3,000 meters, the water temperature is 91 degrees, the Water temperature at 4,000 meters is 88 degrees. and the water temperature at 5,000 meters above sea level is 83 degrees. So when you see water boiling, it doesn't necessarily mean it's 100 degrees.
The world is full of wonders. So far, a German scientist found that the highest water temperature in this vent reached 464 degrees during an investigation into a high-temperature hydrothermal vent at the bottom of the Atlantic Ocean. This temperature It is also the highest water temperature found in the world to date.
A scientist from the Soviet Union discovered a kind of water that does not boil at 100 degrees. It only freezes at minus 40 degrees. It is also very sticky and is called this water. VS'is what we call “polymerized water”! The world of water is always very interesting, with its different shapes, in my life, 100 degrees is the highest temperature I have ever seen in water.
The highest water temperature is 100 degrees. How many degrees coldest can it be?
What is the water temperature? When many people with a little knowledge see this question, the first answer that comes to mind is that water freezes at 0 degrees! Therefore, if it is below 0 degrees, it is ice, and it is not water, so the lowest water temperature is 0 degrees!
This setThe idea is that the pressure requirements are still very high (2000 atmospheres). What if you wanted a more convenient way to produce liquid water at very low temperatures? In fact, you can also do cold water. Ordinary water can reach zerodegree to maximum and freeze below zero. When the density of water is at its maximum, it is between zero and four degrees. In fact, the water temperature does not have to be very low to freeze a person to death. A water temperature of fifteen degrees can cause hypothermia syndrome in some. hours. You will feel that the water is colder than the shore water. Be warm, because if the human body temperature is below 35 degrees Celsius, you risk developing hypothermia syndrome. hypothermia syndrome and freezing to death. It's 0 degrees! I never asked for water. Just like a person, no matter how you practice, you are always yourself. However, if your worldview, outlook on life and values in your ideological field have changed, this will lead to a complete renewal of the essence of a person. Therefore, if you kill people with a simple sign ofhead, why worry too much about life? !
Under standard atmospheric pressure, pure water becomes gaseous above 100 degrees Celsius and becomes solid ice below 0 degrees Celsius. So, under normal circumstances, the highest temperature of water is 100 degrees Celsius and the lowest temperature is 100 degrees Celsius. 0 degrees Celsius.
Water is an inorganic substance composed of hydrogen and oxygen. It is a colorless and odorless transparent liquid at normal temperature and pressure. Water is one of the most common substances, an important resource for the survival of all life, including humans, and the most important component of living organisms. Water has played an important role in the evolution of life. Human beings began to understand water very early. Water is considered a fundamental element in the simple material designs of the East and West. The water is thereone of the five elements of ancient China. Water is also included in the theory of the four elements. of the ancient West.
