_{2}- S

_{1}> ∫

_{1}

^{2}dQ/T

In the case of heat transfer dQ between object with T

_{1}to object with T

_{2}, T

_{1}> T

_{2}

ΔS in Joules/K is known But for evaluating ∫

_{1}

^{2}dQ/T = ln dQ/T - ln dQ/T . d/Q is known but what values for T in this case ?

Object 1 & 2 have Temperatures before heat transfer and different temperature after
