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.
1 When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. 2  Solid water, or ice, is less dense than liquid water.  Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
