Energy is added as heat to 250 g of water at 10°C, raising its temperature one Celsius degree. a) Does this lead to an increase in entropy of the physical system of the H2O molecules? Explain briefly. b) Is there a way to find the change in the sign of the entropy other than counting microstates? c) Determine the change in entropy for the physical system of the H2O molecules.
