Description |
Nederlands: Grafiek van de verdampingswarmte van helium tegen de temperatuur, in 1922 gemeten door Leo Dana. Het kleine dipje bij 2,2 Kelvin, de temperatuur waarbij de dichtheid van vloeibaar helium zijn maximum had, bleek later te duiden op een verandering in de vloeistof: beneden 2,17 Kelvin gaat helium-1 over in helium-11, waarbij allerlei eigenschappen een sprong te zien gaven. (Bijschrift uit de bron.) Natuurkundig Laboratorium, Steenschuur, Leiden. English: Graph of the evaporation heat of helium against the temperature, measured in 1922 by Leo Dana. The small dip at 2.2 Kelvin, the temperature at which the density of liquid helium had its maximum, turned out later to indicate a change in the liquid: below 2.17 Kelvin helium-1 changes into helium-11, with all kinds of properties to see a jump.
