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.
Solubility of gases decreases with water temperature because the water molecules have less affinity for the dissolved gas molecules. So more molecules will leave the water than are entering it. Conversely, solution of solids in liquids increases with temperature.
