Vapor pressure refers to the force exerted by gaseous molecules of a liquid. Usually this is measured in a closed system. For example, in a water bottle some H2O molecules are able to move from liquid to gas phase at room temperature. The molecules that do this create vapor pressure. Low vapor pressure is usually observed in substances that have a low boiling point or if it is being held at a low temperature.
Relative to engine oil, both ethanol (drinking alcohol) and water have low viscosity.

Fresh water is characterized by low salinity levels, typically less than 0.5 parts per thousand. It is essential for sustaining life and is found in lakes, rivers, groundwater, and glaciers. Fresh water is a vital resource for drinking, agriculture, and various industrial activities.

Estuaries and river deltas are areas where rivers pour fresh water into the ocean, resulting in lower salinity levels. The mixing of freshwater with saltwater creates a brackish environment suitable for unique ecosystems to thrive. These areas are important breeding grounds for many marine species due to the nutrient-rich waters.
