Properties of Water Flashcards
percentage of water in body
50-75%
without it, water will be just a gas in room temp.
hydrogen
water’s unique properties results from
intermolecular force - hydrogen bond
5 properties of water
water as a solvent, cohesion/adhesion, density, specific heat capacity, heat vaporization
Water molecules are also attracted to other polar molecules and to ions.
water as a solvent
hydrophilic comes from
hydro - water
philic - loving
hydrophobic comes from
hydro - water
phobic - fearing
Attraction of other molecule of the same kind
cohesion
Water molecules stick to each other.This is due to the hydrogen bonds among the molecules
cohesion
Water molecules stick to each other.
This is due to the
hydrogen bond
Attraction of other molecules of the different kind
adhesion
Water molecules stick to other substances
adhesion
Most plants have adapted to take advantage of water’s adhesion that helps move water from the roots to the leaves. this process is called?
capillary action
This can also be seen as blood moves through our capillaries, carrying nutrients to each cell within our body.
capillary action
the mass per unit of a substance
density
