Water can absorb and store a large amount of heat while increasing only a few degrees in temperature. Why? The heat must first be used to break the hydrogen bonds rather than raise the temperature. The heat must first be used to break the ionic bonds rather than raise the temperature. The heat must first be used to break the covalent bonds rather than raise the temperature. An increase in temperature causes an increase in adhesion of the water. An increase in temperature causes an increase in cohesion of the water. A chemical compound that releases H^+ into a solution is called: a proton. A base. an acid. a hydroxide ion. a hydrogen ion.
