Question

Two quantities of water, of mass M and nM where n is a constant, initially at temperatures T₁and T₂, are adiabatically mixed together, the pressure remaining constant.

(i) Find a change of the entropy in the universe (delta)S, in this process.

(ii) For n = 1, show that (delta)S > 0.

[Hint: you may use (a-b)² for any a and b.]
