Duloxetine is also sometimes used to treat stress urinary incontinence (leakage of urine during physical activity such as coughing, sneezing, laughing, and exercise) in women. Talk to your doctor about using this medication to treat your condition.
Water's density maximum is a product of the same phenomenon. Close to the freezing point, the water molecules start to arrange locally into ice-like structures. This creates some openness in the liquid water, which tends to decrease its density.
Freezing is also exothermic, and the entropy of the surroundings will increase. The equation for the entropy of the surrounding is the opposite the heat of the reaction which during a phase change, which is at equilibrium so the process is reversible.This means that the entropy of the surroundings will increase.here is the system, which is the water freezing. There is the surroundings, which I just discussed, which is the environment of the reaction, all of the universe except the reaction. Then there is the entropy of the universe, which is always increasing.
