Temperature is an ordinary operation in the history of human civilization improvement, due to the learning to often use inorganic substances to make flames. We human beings have only transitioned from drinking blood to cooked food, and have gradually developed a common food civilization. With the rapid improvement of science and technology, with the assistance of modern physics, we human beings have slowly made it clear that in addition to the temperature will increase, the similarity will also decrease, and the relative zero degree is the lowest limit of temperature. What we said that day was relative zero, so do you know what the relative zero is? Let's find out together!
Modern thermodynamics tells us that the temperature can increase and decrease at the same time. At present, we human superstitious people have studied this relative zero degree and obtained the result of -27315 degrees Celsius. At such a low temperature, the molecules of the object have no potential energy and kinetic energy, and the external energy of the object is also zero at the moment when the kinetic energy is zero. That is, at the moment of relative zero, there is no heat and energy in any matter.
According to the analysis of the third law of modern thermodynamics, this relative zero degree is basically impossible to reach in the current state, and the only or limited imminence is possible. Because any space, whether large or small, has or has some heat and energy. These energies will only be converted all the time and will not be hidden, so this relative zero degree basically does not exist in this world, unless there is no heat and energy outside the space, which means that the total volume of space must be zero to reach the relative zero degree.
Although this relative zero degree does not exist outside the artificial world, outside the vacuum universe, such a situation does exist. Astronomers once discovered that there is a universe called the Pullback Bar Nebula. The temperature in the Pullback Bar Nebula is minus 272 degrees Celsius, which is the coldest known outside the universe**, so it is called the cosmic ice box. The temperature of this universe is only one degree away from reaching relative zero.
1) According to the inscription, when t=-273 and t=0, the conversion relationship between the thermodynamic temperature t and the Celsius temperature t is t=273+t; (2) When t=37, t=(273+37)k=310k Answer: The conversion relationship between thermodynamic temperature and Celsius temperature is t=273+t; The temperature of a healthy human body is 37, if expressed as thermodynamic temperature should be 310K
This is because the temperature of an object is actually the movement of atoms inside the object.
When we feel that an object is hot, it means that its atoms are moving fast: when we feel that an object is colder, it means that the atoms inside it are moving slowly.
Our bodies sense this movement through heat or cold, while physicists measure temperature on the absolute temperature scale, or Kelvin temperature scale.
Measuring temperature according to this temperature scale, an absolute temperature of zero degrees (0 K) is equivalent to minus 273 degrees Celsius15 degrees (-273.)15) Known as "absolute zero", it is the lowest possible temperature in nature.
At absolute zero, the motion of the atoms stops completely, and theoretically, the volume of the gas should be zero.
Virtually all actual gases at temperatures close to -27315 , the gas will exhibit significant quantum properties, by which time the gas has long since become liquid or solid.
From this, we will understand why it is impossible for the temperature to fall below this scale, and why it is in fact impossible to even reach this scale, but only to approach it.
Absolute zero minus 27315 degrees At this time, the molecules of matter are basically not moving.
There is a lower limit of temperature in the universe: -27315 degrees Celsius, i.e. 0 degrees thermodynamically, proves that thermodynamic zero degrees are unattainable and the lowest temperature we have obtained in the laboratory (laser cooling method) is 24 times 10 to the minus 11 degrees Kelvin (very close to 0 K), the lowest temperature naturally occurring on Earth is -88 degrees Celsius at the South Pole.
The theoretical minimum temperature of the universe is -27315 , which is absolute zero.
Microscopically speaking, the temperature is the intensity of the molecular thermal motion of the object, the more intense the molecular thermal motion, the higher the temperature, and when all the atomic and molecular thermal motion is stopped, the minimum temperature is reached—27315℃。
The lowest temperature in the world is: theoretically absolute zero, -27315℃。
The absolute temperature of zero (0K) is equivalent to -273 degrees Celsius15 degrees (-273.)15) Known as "absolute zero", it is the lowest possible temperature in nature.
