Why is there a zeroth law of thermodynamics? What use is such a simple-sounding law? And how can it be used to smash glass? Chemical engineer Valeska Ting explains in the first film from our 2016 advent calendar, all about thermodynamics. • Visit the online advent calendar: http://www.rigb.org/advent?utm_source... • Subscribe for regular science videos: http://bit.ly/RiSubscRibe • The first, second and third laws of thermodynamics get all the glory. They’re the most well known and frequently mentioned. But underpinning them all is a final law so fundamental that, although it was established last, had to be moved to the front of the list: the zeroth law. In the first film of our 2016 advent calendar, chemical engineer Valeska Ting explores the zeroth law of thermodynamics. • The zeroth law is essentially an observation: if two systems are both in thermal equilibrium with a third, they are also in equilibrium with each other. This seemingly simple mantra is essential to our concept of temperature, as Valeska, armed with some very hot glasses, explains. • Our 2016 advent calendar explores the four laws of thermodynamics through 24 short films, released daily in the run up to Christmas. We’ll have explosive demonstrations, unique animations and even a musical number.
