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.
Big Idea: Salt causes water to freeze at a lower temperature. Sea ice forms only under very cold conditions (e.g., near Earthâs poles) because of its salinity (i.e., presence of dissolved salt). Key Concepts: â¢ Dissolving any substance in pure water raises or lowers the freezing and boiling point.
