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.
There is more evaporation from hot water rather than from cold water. Thus, the evaporation not only carries off some of the water, resulting in slightly less water to freeze in the warm water container, but it also causes the temperature of the warm container to drop due to heat lost.
