Properties of water Flashcards
Properties of water
Water as solvent
Cohesion/adhesion
Density
Specific Heat Capacity
Heat of Vaporization
attraction of molecules of the same kind and water molecules have strong cohesive forces thanks to ability to form hydrogen bonds w/one another.
Cohesion
refers to the attraction of molecules for other molecules of a different kind.
Adhesion
Bigat or mass water
solid form due to its oriented hydrogen bonds as it freezes
Density
Density of liquid water
1g/cm³
density of Ice
0.9168g/cm³
its less dense, ice floats on the surface of the liquid water
buoyance
is the specific heat needed to raise the temperature of one gram of substance by one degree celcius
