Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy … See more At temperatures near 0 K (−273.15 °C; −459.67 °F), nearly all molecular motion ceases and ΔS = 0 for any adiabatic process, where S is the entropy. In such a circumstance, pure substances can (ideally) form See more Absolute, or thermodynamic, temperature is conventionally measured in kelvin (Celsius-scaled increments) and in the Rankine scale (Fahrenheit-scaled increments) with … See more One of the first to discuss the possibility of an absolute minimal temperature was Robert Boyle. His 1665 New Experiments and Observations touching Cold, articulated the dispute known as the primum frigidum. The concept was well known among … See more • Physics portal • Kelvin (unit of temperature) • Charles's law • Heat See more A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and … See more Temperatures that are expressed as negative numbers on the familiar Celsius or Fahrenheit scales are simply colder than the zero points of those scales. Certain systems can achieve truly negative temperatures; that is, their thermodynamic temperature (expressed … See more The average temperature of the universe today is approximately 2.73 kelvins (−454.76 °F), or about −270.42 ºC, based on measurements of cosmic microwave background radiation. Standard models of the future expansion of the universe predict that the average … See more WebLo zero assoluto è la temperatura minima possibile teorica di un qualsiasi sistema termodinamico.

El cero absoluto es la temperatura más baja posible. A esta temperatura el nivel de energía interna del sistema es el más bajo posible, por lo que las moléculas, según la mecánica clásica, carecen de movimiento; no obstante, según la mecánica cuántica, el cero absoluto debe tener una energía residual, llamada energía de punto cero, para poder así cumplir el principio de indeterminación de Heisenberg. El cero absoluto sirve de punto de partida tanto para la escala de Kelvin como para … WebO kelvin é a fração 1/273,16 da temperatura termodinâmica do ponto triplo da água, ou seja, é definido de tal modo que o ponto triplo da água é exatamente 273,16 K.
