QR Challenge: Marine Biology Properties of Water QR Review

QuestionAnswer
Which end of a water molecule has a slightly positive charge?hydrogen end
What term refers to a molecule that shares its electrons unequally?polar
Which unique property of water allows it to regulate temperature?high specific heat
What term refers to a substance, like water, that can dissolve many different types of materials?universal solvent
What two processes increase the amount of freshwater entering the ocean and therefore decreases salinity?precipitation and runoff
What type of intermolecular bond forms between two or more molecules of water?hydrogen
What happens to the density of water when it freezes into a solid?the density decreases
What happens to the density of water as its temperature decreases?the density increases
What is the average salinity of the ocean?35 ppt
What type of bond holds the atoms of hydrogen and oxygen together in an individual water molecule?covalent
What term refers to water's ability to stick to other substances?adhesion
What process increases the salinity of the ocean?evaporation
At 32F or 0C, will seawater freeze?Explain your answer.No, because sea water has a lower freezing point than pure, freshwater
What term refers to the thickness of a fluid or a fluid's tendency to resist flow?viscosity
What term refers to water's ability to stick to other water molecules?cohesion
Why does the oxygen end of a water molecule have a slightly negative charge?because it is larger and pulls the negatively charge electrons toward its end of the water molecule
What term refers to the film-like quality on the surface of a liquid produced by cohesion?surface tension
What are the three phases (states) of water?ice(solid), water(liquid), water vapor(gas)
How many hydrogen bonds can an individual molecule form at a single time?4
What two types of compounds will dissolve in water?ionic and polar covalent
