Q4. A piece of copper having a mass of 10 kg at atemperature of (810) K is dropped into a well – insulated tank containing (100) kg of water at a temperature of (294) K. if the specific heat of copper and water are (0.095) and (1) kcal/kg. k respectively. Calculate the resulting changes in entropy of water and copper. Then calculate the total entropy change resulting from the process. Ans: 4Scopper=- 0.929 kcal/k, aSuater-3.5, ASr=2.57kcal/k

Transcribed Image Text:Q4. A piece of copper having a mass of 10 kg at atemperature of (810) K is dropped into a
well – insulated tank containing (100) kg of water at a temperature of (294) K. if the specific
heat of copper and water are (0.095) and (1) kcal/kg. k respectively. Calculate the
resulting changes in entropy of water and copper. Then calculate the total entropy change
resulting from the process. Ans: 4Scopper= - 0.929 kcal/k, ASnater=3.5, AS1=2.57kcal/k
