A 2.1 kg sample of water at 35 degrees Celsius is poured into a lake. The temperature of the lake water is 10 degrees Celsius, and it remains essentially constant as the 2.1 kg sample cools down within it. What is the entropy change of the lake water? Let the specific heat capacity of water = 4190 J/(kg*K)
