What is the Zeroth Law of Thermodynamics?
Δημοσιεύτηκε στις 1 Δεκ 2016
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.

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.
