Liquid water can be assumed to be incompressible for most purposes: its compressibility ranges from 4.4 to 5.1 × 10 −10 Pa −1 in ordinary conditions. [99] Even in oceans at 4 km depth, where the pressure is 400 atm, water suffers only a 1.8% decrease in volume.
A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique (' opposite to the Arctic ') and, in turn, the Latin antarcticus (' opposite to the north ').
The measurement of pH can become difficult at extremely acidic or alkaline conditions, such as below pH 2.5 (ca. 0.003 mol/dm 3 acid) or above pH 10.5 (above ca. 0.0003 mol/dm 3 alkaline). This is due to the breakdown of the Nernst equation in such conditions when using a glass electrode.
[15] [16] A 1:1 mixture of toluene and 1,4 dioxane has δD, δP and δH values of 17.8, 1.6 and 5.5, comparable to those of chloroform at 17.8, 3.1 and 5.7 respectively. Because of the health hazards associated with toluene itself, other mixtures of solvents may be found using a full HSP dataset.
The population of Finland is about 5.6 million. The birth rate is 7.8 per 1,000 residents, for a fertility rate of 1.26 children born per woman, [213] one of the lowest in the world, significantly below the replacement rate of 2.1. In 1887 Finland recorded its highest rate, 5.17 children born per woman. [214]
