2.5 Properties of Water Flashcards
1
Q
Cohesion
A
Between H2O molecules, creates surface tension
2
Q
Adhesion
A
Between H2O and another molecule, creates capillary action
3
Q
Universal Solvent
A
Polarity makes H2O a good solvent
4
Q
Hydrophilic
A
Dissolves in water and polar
5
Q
Hydrophobic
A
Doesn’t dissolve in water and nonpolar
6
Q
Ice
A
Less dense as solid, Surface ice insulates water below, seasonal turnover
7
Q
High Specific Heat
A
H2O has a high specific heat, resists change in temperature
8
Q
Heat of Vaporization
A
Break Hydrogen bonds to evaporate, evaporative cooling
