APB G1a L8 Properties of Water matching

acid

a substance that donates H+ ions to a solution

adhesion

hydrogen bonds hold molecules of different substances together

base

a substance that accepts H+ ions from a solution

cohesion

hydrogen bonds hold molecules of the same substance together

density of ice

solid water is less dense than liquid water

high heat of vaporization

water can absorb a lot of heat before it changes from a liquid to a gas

high specific heat capacity

water can absorb a lot of heat before the temperature of the water changes

hydrogen bonds

bonds that form between polar molecules

nonpolar covalent bond

bond where electrons are shared equally due to similar electronegativities

pH

a measure of the H+ concentration

polar covalent bond

bond where electrons are not shared equally due to differences in electronegativity

polarity

characteristic of a molecule with a partial positive charge on one region and a partial negative charge on another region

denaturation

the unfolding of a protein due to unfavorable pH, temperature, etc
