Can kelvin be negative
WebJan 10, 2013 · According to the physical meaning of temperature, the temperature of a gas is determined by the chaotic movement of its particles — the colder the gas, the slower the particles. At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. WebSep 8, 2015 · Based on the Boltzmann factor, this can't be possible unless the temperature of the system is negative. That is, P 1 P 2 = e − ( E 1 − E 2) k T which approaches …

Usually, system temperatures are positive. However, in particular isolated systems, the temperature defined in terms of Boltzmann's entropy can become negative. See more Certain systems can achieve negative thermodynamic temperature; that is, their temperature can be expressed as a negative quantity on the Kelvin or Rankine scales. This should be distinguished from temperatures … See more Negative temperatures can only exist in a system where there are a limited number of energy states (see below).

WebKelvin is the SI base unit of temperature. It is given the symbol .Since temperature measures the energy of atoms and molecules, a true temperature scale must be a positive scale since atoms cannot have a negative energy.

They tell you correctly that a Kelvin value can't be negative, T > 0 K. Also, they should have told you that a degrees Celsius value can't be below T > − 273.15 ∘ C. Sure, you can make up a number below this value, such as − 275 ∘ C. Just like you can make up a number such as − 10 K. These numbers just don't represent reality.
WebDec 20, 2024 · Kelvin is measured from when molecules have stopped moving completely. It isn't possible to get lower than not moving. They did discover these negative Kelvin degrees in a quantum gas or similar, but how they derive it's lower than 0 Kelvin is lost on me. Negative density is something else however.
