Lecture 4: 09.16.05 Temperature, heat, and entropy
... o� Why would two metals heated to the same temperature have a different ability to melt the wax strip? The answer lies in the equation above relating temperature and heat, which indicates that two metals at the same temperature have not necessarily received the same amount of energysince the amount ...

... can pair up with opposite spins so that two 3 He atoms can occupy each translational energy state. However, in solid liquid 3 He, the atoms are centered on lattice sites and the wavefunctions do not overlap much. So the spins on different atoms in the solid are not correlated and the spin entropy is ...

Inexistence of equilibrium states at absolute negative temperatures
... The previous known result [7] prompted Ramsey [2] to review the statements of the Second Law such that negative temperatures would not violate it. The main goal of Ramsey was to identify negative temperatures using the relation (2) in a well defined cyclic process. He certainly achieved it, as we sh ...

The heat capacity depends on the material, but moreover it depends on the process by which the heat is added. If we consider isobaric and isochoric process, then the corresponding heat capacities ...
