An object of mass m1, specific heat c1 and temperature T1 is brought into contact with a second object of mass "'2, specific heat c2 and temperature T2 > T1. At the temperature of the first object increases to T and the temperature of the temperature of the second object decreases to T'. (a) Show that the entropy increase of the system is given by the expression in figure 1 and show that conservation of energy requires what is shown in figure 2 (b) Show that the entropy change /l.S, considered as a function of of T, becomes maximum when T = T'

(b) Show that the entropy change /l.S, considered as a function of
of T, becomes maximum when T = T', which is precisely the condition
thermodynamic equilibrium condition. (e) Discuss the result
of item (b) considering the idea that entropy indicates the degree of disorder
of disorder of a system.
