Water density is a measure of how much mass is contained in a given volume of water, typically expressed in grams per cubic centimeter (g/cm³). It varies with temperature and salinity, with pure water reaching its maximum density at 4°C and decreasing as it warms or cools from this point.

Mass is a fundamental property of physical objects that quantifies the amount of matter contained within them, playing a crucial role in the laws of physics, especially in mechanics and gravitation. It is invariant in classical physics but can vary according to the theory of relativity when an object approaches the speed of light.

Temperature is a measure of the average kinetic energy of the particles in a substance, which determines how hot or cold that substance feels. It plays a critical role in various scientific disciplines, influencing physical states, chemical reactions, and biological processes.

Salinity refers to the concentration of dissolved salts in water, a critical factor influencing the density and circulation of ocean currents, as well as the health of aquatic ecosystems. It is measured in parts per thousand (ppt) and can vary significantly due to factors like evaporation, precipitation, and freshwater inflow from rivers.
