Liquid water is a very good heat storage medium – anyone with a Thermos bottle knows that. However,as soon as water boils or freezes, its storage capacity drops precipitously. Physicists at the University of Bonn maintain now observed very similar behavior in a gas of light particles. Their findings can be used, and for example,to produce ultra-precise thermometers. The work appears in the prestigious technical journal Nature Communications.
