The lowest possible temperature, or absolute zero as it is called, is -459.67Â°F (-273.15Â°C). It is also called 0 kelvin, a scale with increments equivalent to degrees of Celsius, but which uses absolute zero rather than water's freezing point as its starting point. This is the point at which all atomic motion ceases.
[Middle English foundren, to sink to the ground, from Old French fondrer, from Vulgar Latin *funderÄre, from *fundus, *funder-, bottom, from Latin fundus, fund-.] Usage Note: The verbs founder and flounder are often confused. Founder comes from a Latin word meaning bottom (as in foundation) and originally referred to knocking enemies down; it is now also used to mean to fail utterly, collapse.. Flounder means to move clumsily, thrash about, and hence to proceed in confusion..
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an aeroplane. Other kinds of partition elements within a ship are decks and deckheads.ong Dynasty author Zhu Yu (fl. 12th century) wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book Garden of Strange Things by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking.
