Topic:Physics statistics

1 a)Give definition of absolute temperature through entropy. Using microcanonical formalism,show that for two systems in a state of thermal equilibrium with each other, the equality of temperatures follows from the fact that entropy is an extensive quantity.

b)Explain if the absolute temperature can be negative or not. If so, in what physical systems and why does this phenomenon happen?

Expert Solution

For some spin states negative temp. State has been achieved.For thermodynamically stable system absolute temp. Can never be negative.

Problem #1 : Using separation of variables and the formalism demonstrated in class, find the general solution to the Helmholtz equation (also known as the time independent wave equation) : ∇^2 F + k^2 F = 0 Assume that k is a real number. For clarification, the general solution is the solution in the case where boundary conditions are not specified. Problem #2 : Express the following functions as an infinite Fourier sine series using sin(nπx/a) a)f(x) = x b)f(x)...
