Description

Students introduced to thermodynamics often struggle with the distinctions between temperature, heat, and internal energy, concepts all used more or less interchangeably in everyday life or in pop-science but which have precise and distinct definitions in physics. In this talk I will highlight how physical systems with negative heat capacity, for which spontaneous energy losses correlate to increases in temperature, can be used to make the distinctions more easily understandable at a conceptual level.
