Question 3 Entropy a) For a heat reservoir (T= 400 K), the power lost to the surrounding is 500 W. Find the rate of entropy change of the heat reservoir. b) 2 kg of clod water is mixing with 5 kg of hot water, the temperature of clod water and hot water are 20°C and 90°C respectively. Find the overall entropy change.
