polarity of water molecules, where the oxygen atom is slightly
negative, and the hydrogen atoms are slightly positive. The
positive hydrogen of one molecule is attracted to the negative
hydrogen bonding oxygen of another, forming hydrogen bonds.
Surface tension (due to cohesion) allows insects like water striders to walk on
water.
Capillary action (cohesion + adhesion) helps water move up plant roots and
stems against gravity. (hydrogen Bonds)
high specific heat A property of water. Water can absorb lots of heat before
changing temperature
when liquid evaporates surface cools down ( why dogs pant)
The orientation of hydrogen bonds causes molecules to push
farther apart, which lowers the density. (allows for life in
Why ice is less dense
Antarctica, so its not completely frozen)
than water
Why is water being a human body, water dissolves nutrients, salts, and gases,
universal solvent allowing them to be transported via blood to cells. Water also
helps facilitate chemical
important
reactions, like digestion, by dissolving food molecules and
enzymes.
Morality formula M=mol/L
molar mass the mass of one mole of a pure substance
Determines how much thermal energy is needed to change the
temperature of a substance, and substances with higher specific
heats can absorb more thermal energy with smaller temperature
changes.
