Dear,

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

  • Kelvin defined the absolute temperature scale in the mid-1800s in such a way that nothing could be colder than absolute zero.
  • Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles.
  • Absolute zero corresponds to the theoretical state in which particles have no energy at all, and higher temperatures correspond to higher average energies.
  • Physicists have created an atomic gas with a sub-absolute-zero temperature for the first time.
  • Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.
