Absolute zero! Stop, stop. In fact, this temperature is not quite "zero"
Interesting fact: absolute zero in temperature, not exactly zero. In a literal sense, the absolute temperature zero is understood as the lowest possible temperature mark on the thermodynamic scale of temperature, that is, the Kelvin scale. The unit for measuring such temperature is named after the greatest English physicist, William Thomson, who at one time was awarded the title of Kelvin Largsky from Ayrshire for his achievements in the field of physics. The English Royal Family. In turn, the title itself is named after the English Kelvin River (River Kelvin). Kelvin flows through the entire territory of the University of Glasgow.
In the middle of the twentieth century, namely in 1954, the general conference on the installation of measures and weights made original conclusions about the thermodynamic temperature.To be perfectly accurate about the triple point of water. Interestingly, according to the conclusions of the conference, the beginning of the Kelvin thermometer scale coincides with the absolute zero. Also, interesting is the fact that in the thermometer there is no mark below. In terms of degrees Celsius, the absolute zero or zero Kelvin is equal to, no less than, minus 273.15 degrees. And the temperature of the triple point of water is 0.01 degrees Celsius.
An interesting fact: when the water temperature approaches the absolute zero system, it creates separate flows for entropy, heat capacity, as well as for CTE (coefficient of thermal expansion in this case of water). Almost instantly, the movement of particles that are constantly in chaos and the system is destroyed stops. In other words (“translated into simple language”), a substance not only becomes superfluid, but also superconducting, that is, it practically becomes a super-substance. Recall that this is just water.
An interesting fact: in practice, to achieve absolute zero or zero in Kelvin is not realistic. Conclusions are made on the basis of approaching the thermometer to the mark of absolute zero. In general, attempts to achieve absolute zero,Today they create a fairly large problem in science and do not provide an opportunity to prove or, on the contrary, refute many assumptions and very hasty conclusions. However, temperatures have already been obtained only by millions of degrees lagging behind absolute zero.
Without a doubt, science has stepped far forward since the discovery of absolute zero. A little bit more and we will get accurate information about this wonderful phenomenon.
An interesting fact: according to sociological surveys conducted in the United States of America, only forty percent of the respondents know what an absolute zero is. When the scientists finally reach the absolute zero point in Kelvin, then the secret of the super substance will be revealed. Science keeps many secrets and agadak. Today, after reading this article, you have revealed the secret of zero in Kelvin or 273.15 Celsius. And yes, do not forget, there are still many measuring instruments bearing the names and titles of other famous people who also calculate degrees. For example, recently in universities in the United States, it has become “fashionable” to calculate temperatures in Fahrenheit, and then convert it to Celsius or Kelvin.
