A1.1 - WATER - Coggle Diagram
A1.1 - WATER
PHYSICAL PROPERTIES
Buoyancy
upward force applied to an object
Viscosity
resistance to movement
Thermal Conductivity
medium’s ability to move heat across a temperature gradient
Specific Heat Capacity
amount of energy required to raise the temperature of 1g of substance by 1ºC
ADHESION
water molecule & other polar molecules (surfaces)
flow in opposition to gravitational force
CAPILLARY ACTION
water up in the plant stems
SOLVENT PROPERTIES
medium for metabolic reactions
NOT A UNIVERSAL SOLVENT
EG. ENZYMES
Transport Medium
movement of water-soluble substances in plants and animals
BLACK THROATED LOON VS. RINGED SEAL
BLACK THROATED LOON
floats better on water (buoy,)
preventing heat loss (water has higher thermal conductivity)
RINGED SEAL
denser bones (less buoyant)
higher viscosity
medium for life
everything originated in water
2 hydrogen atoms covalently bonded to an oxygen atom
unequal sharing of electrons=
POLARITY
OXYGEN= (δ–)
HYDROGEN= (δ+)
Hydrogen bonds= between water molecules
Covalent bonds= within water molecules
HYDROGEN BONDS
WEAK intermolecular associations
COHESION
water molecule & other water molecules
THANK U HYDR.BONDS
SURFACE TENSION
RESULT OF HYDROGEN BONDING
CONDUCTION OF WATER IN THE XYLEM
suck water up to the tops of the tallest trees
