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.
A unique property of water is that its density increases at 4Â°C (39Â°F), just before it hits. freezing temperature. This causes water at this temperature to sink to the bottom of the. pond or lake. When water molecules do freeze, the ice is less dense than the 4Â°C water, causing it to float on the surface. The differences in density start mixing the top and. bottom layers of water. This mixing of the water layers as air temperatures become. colder is called fall turnover (Fig. 1).
