The total entropy change is 1.036 JK/K
Entropy means the unavailable energy associated with the system. The entropy generation for the reversible cycle is zero and for irreversible cycle, it is positive. We can also understand entropy to be randomness of a system, Randomness is maximum in gaseous state and least in solid state.
The given data; the amount of heat transferred by the thermal reservoir is Q = 100KJ. Temperature of the high thermal reservoir is [tex]T_{h}[/tex] = 1150k.
The temperature of the low thermal reservoir is [tex]T_l[/tex] = 600K.
[tex]d_{s}[/tex] = -Q + Q
[tex]T_{h}[/tex] [tex]T_{l}[/tex]
Substituting the formula we get
[tex]d_{s}[/tex] = - 100KJ + 1OOKJ
1150K 600K
= 1.036 KJ/K
