2.1.1. Density Density is an important physical characteristic of any substance, and is a measure of the mass per unit of volume of that substance. It is an accepted fact that vegetable oil density decreases linearly with increasing temperature. This rela-tionship can be expressed mathematically as [27], r ¼ aþb,T (1)

Density is defined as the mass per unit volume. Dissolved salts and changes in temperature alter the density of a water sample. Freshwater is less dense than saltwater at a given temperature. Density of pure water increases with decreasing temperature until about 4 ºC, at which point the density decreases.

Seawater density is a function of both temperature and salinity. The density increases with either a temperature decrease or a salinity increase. Under normal ocean conditions, temperature fluctuations exert a greater influence on seawater density because the range of marine temperatures values is much greater (-2( C to 30( C) than the range of ...

Properties of Water Station Lab Station 5. Density. Water is one of the few substances that are less dense as a solid than as a liquid. While most substances contract when they solidify, water expands. This property is due to the hydrogen bonding between water molecules. Part 1. Place the ice cube in the water.
