Definition of density Density refers to how tightly packed molecules are in a specified space. Expressed as mass per unit volume or g/cm 3 Density is affected by state (gas, liquid, solid), temperature, salinity & pressure

Unformatted text preview: water) the densest water is formed in fall as temperatures begin to drop. When surface water temperatures fall below 4C, surface water stops sinking to the bottom of the lake and ice can begin to form. Salinity changes liquid water density Sal t ion But does seawater reach its maximum density at 4C? The temperature of the maximum density of seawater with a salinity of 24.7 is -1.33C. BUT WAIT.doesnt water freeze at 0C Not so in the oceans What latitude are the coldest temperatures? a.90 b.60 c.30 d.0 What latitude are the saltiest ocean waters? a.90 b.60 c.30 d.0 What latitude are the densest ocean waters? a.90 b.60 c.30 d.0...
