Transcript of Thermodynamics

ABSOLUTE ZERO The lowest theoretical temperature at which entropy reaches its minimum So What is Absolute Zero? ITS COLD Presented By:
Cody Chlanda & Tyrone Hou This means that there is
no molecular movement AT ALL! Tert-Butyl Alcohol Triple Point So can you reach
absolute zero? Probably not... ...Close, but no cigar... 0 K -459.67 F -273.15 C 0.0000000001 K ...Only a Nobel Prize... So what happens when you get close to absolute zero? Cornell Wieman Ketterle (NO!) THE PROOF How about 7 Second Law of Thermodynamics:
The entropy of any isolated system not in thermal equilibrium almost always increases. Third Law of Thermodynamics:
The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. How many states of matter are there? 4? 5? 2001 BABY!!! Bose Einstein Condensate (BEC) In 1938 Fritz London proposed BEC as
a mechanism for superfluidity in Helium-4 Fermionic Condensate A superfluid is a state of matter with several unusual physical properties including... Zero Viscosity The ability to flow without
dissipating energy Rollins Film (Closest to a liquid) Quark Gluon Plasma First discovered in 1925 by Satyendra
Nath Bose and Albert Einstein Discovery of Debra Jones in 2003 Quarks: particles
Gluons: intermediary forces What About Absolute Hot? Solid Liquid Gas Plasma 1.416785(71) × 10^32 K
Planck Temp Max Planck Rolf Hagedorn
(string theory) No,
10^30 K
