Water
- H bonds
- O has partially -ve
charge H had partially
+ve charge
- Not strong bonds +
can only form with N,
F and O
- O has partially -ve
charge H had partially
+ve charge
- high latent heat of vaporisation /
large amount of energy required to
change from liquid to gas
- evaporation is (efficient) cooling mechanism
- E.g panting
in dogs
cools them
- E.g panting
in dogs
cools them
- evaporation is (efficient) cooling mechanism
- ice, is less dense
than water / floats
- (surface of) ice provides habitat for,
organisms e.g. polar bears
- (surface of) ice provides habitat for,
organisms e.g. polar bears
- high specific heat capacity / large
amount of energy needed to, raise /
change, temperature
- (thermally) stable
environment for, aquatic /
named aquatic, organisms
- (aquatic) organisms
use less energy on
temperature control
- 4 (internal) temperature
of organisms changes
only slowly
- (biological) reactions / enzymes
/ metabolism, function(s)
correctly
- (aquatic) organisms
use less energy on
temperature control
- (thermally) stable
environment for, aquatic /
named aquatic, organisms
- water (beneath ice),
insulated / remains liquid /
doesn’t freeze
- (aquatic) organisms, do not
freeze / can still swim
- (aquatic) organisms, do not
freeze / can still swim
- (effective) solvent
- medium for reactions /
(internal) transport medium /
able to dilute toxic substances
- medium for reactions /
(internal) transport medium /
able to dilute toxic substances
- cohesion / adhesion
- allows formation transpiration stream /
apoplast movement
- allows formation transpiration stream /
apoplast movement
- surface tension
- habitat for invertebrates e.g. pond
striders
- habitat for invertebrates e.g. pond
striders
- transparent so allows
underwater
photosynthesis
- is high density so
allows
flotation/support
- organisms can still obtain,
oxygen/minerals/food/carbon
dioxide from water
