Q. The entropy of a sample of a certain substance increases by $0.836\, J\, K^{-1}$ on adding reversibly $0.3344\, J$ of heat at constant temperature. The temperature of the sample is:

AIEEEAIEEE 2012Thermodynamics

Solution:

$\Delta S=\frac{\Delta H}{T}; T=\frac{\Delta H}{\Delta S}=\frac{0.3344}{0.836}=0.4\,K$
