Properties of Water - Honors Biology

STUDY
PLAY
cohesion
Water molecules stick to each other as a result of hydrogen bonds
adhesion
Water molecules stick to other substances (ex: water up a plant)
surface tension
Measure of how difficult it is to stretch or break the surface of a liquid
temperature stabilization
absorbs heat from air and releases itt to where it's cooler
high specific heat
heat must be absorbed to break hydrogen bonds, and heat is released when hydrogen bonds form
evaporative cooling
molecules move fast enough to overcome the attractions between them can depart the liquid and enter the air as gas
expands when frozen
water expands because of hydrogen bonding hydrogen bonds keep the molecules at "arms length"
solution
a liquid that is a mixture of hydrogen bonding
hydrophilic
"water loving" - a substance that has an affinity for water
hydrophobic
"water fearing" - a substance that does not have an affinity for water
acids
higher concentration of H+/ have pH less than 7
bases
higher concentration of oH-/have pH more than 7
buffers
internal pH of most living cells cells/close to 7/minimize changes in pH
solvent
the dissolving agent
solute
the substance that is dissolved
ionic bond
electrons are transferred from one atom to another-STRONG
covalent bond
electrons are shared among atoms-STRONG
hydrogen bond
weak bonds formed between molecules that have weak partial charges
polarity
partial negative with hydrogen/ opposite charges opposite elements
