Imagine that the seawater sample previously at 0◦C is now heated to 17◦C with no change in salinity. Its density (to the fourth decimal place) is now g/cm3.
Homework Answers
The density of seawater at 0°C is 1.0273g/cm3.
The volumetric coefficient expansion of water is 0.000214/°C, which means that a unit volume of water increases in volume by 0.000214 units per °C. Thus, in 17°C, the volume of water increases by 0.000214x17 = 0.003638.
Thus, the new seawater has a volume of 1.003638 per unit volume of old seawater. The mass per unit volume however remains constant.Thus, the density changes from 1.0273 to 1.0273/1.0036 = 1.0236g/cm3
