    en.wikipedia.org/wiki/Properties_of_water

    Water is amphoteric: it has the ability to act as either an acid or a base in chemical reactions. [87] According to the Brønsted-Lowry definition, an acid is a proton (H +) donor and a base is a proton acceptor. [88] When reacting with a stronger acid, water acts as a base; when reacting with a stronger base, it acts as an acid. [88]

    Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H +, that is, a proton) donor, can be neutralized by a base, a proton acceptor such as a hydroxide ion (OH −) to form water. Water is considered to be neutral, with a pH (the negative log of the hydrogen ion concentration) of 7 in an ideal state.

    The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...

    When water freezes, it increases in volume (about 9% for fresh water). [8] The effect of expansion during freezing can be dramatic, and ice expansion is a basic cause of freeze-thaw weathering of rock in nature and damage to building foundations and roadways from frost heaving. It is also a common cause of the flooding of houses when water ...

  7. Stratification (water) - Wikipedia

    en.wikipedia.org/wiki/Stratification_(water)

    The thermal stratification of lakes is a vertical isolation of parts of the water body from mixing caused by variation in the temperature at different depths in the lake, and is due to the density of water varying with temperature. [14] Cold water is denser than warm water of the same salinity, and the epilimnion generally consists of water ...
