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.
The more salt in the water, the lower the freezing point will be. When freshwater freezes, water molecules of hydrogen and oxygen have bonded together into a crystalline structure of ice. The presence of salt makes it harder for water molecules to bond to the ice structure, because ice naturally repels salt molecules.
