The vapor pressure of the water is lowered whenever a solute is added to a solvent because there are fewer solvent particles on the surface to evaporate. The diagram above shows that the vapor pressure of the solution is lower than that of the pure solvent, Therefore, the freezing point is also lowered.
Watch for signs of cervical dilation if you are near the end of your pregnancy. This indicates that you are in labor, and it's time to talk with your doctor or midwife. As the baby's head begins to press down on the opening of the uterus, the cervix will start to thin out and open.
