Question

what happened in the area where heat and cold together​

Answer 1

Answer:

Temperature is a very useful physical quantity. It allows us to make a simple statistical statement about the energy of particles swirling around on complicated paths without having to know the specific details of the system. Scientists from the Vienna University of Technology together with colleagues from Heidelberg University have now investigated, how quantum particles reach such a state where statistical statements are possible. The result is surprising: a cloud of atoms can have several temperatures at once. This is an important step towards a deeper understanding of large quantum systems and their exotic properties.
