Under normal Earth sea-level conditions water boils at how many degrees centigrade?
Sea level the warmer water expands. For at least the last 100 years, sea level has been rising at an average rate of about per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper of sea water. Additional contributions, as much as one-quarter of the total, come from water sources on land, such as melting snow and glaciers and extraction of groundwater for irrigation and other agricultural and human uses. Pilots can estimate height above sea level with an altimeter set to a defined barometric pressure.
Normal conditions be found. l Normal conditions Normal conditions are a restriction on philosophical arguments, especially in epistemology, in order to avoid objections perceived as digressive. As a reply to objections to an explanation of a phenomenon, e.g. a hypothesis or a theory, it is said, argument X holds [only] under normal conditions. In some cases, the concept of normal conditions tends to be rather blurred and the reply under normal conditions can tend to extend to everything that contradicts an argument. In cases, when the argument of normal conditions comes too often, according to the principle of Occam's Razor another explanation
