Plimsoll (surname)
Plimsoll is a surname. Notable people with the surname include: * James Plimsoll (1917–1987), Australian diplomat and public servant * John Plimsoll (1917–1999), South African cricketer * Samuel Plimsoll Samuel Plimsoll (10 February 1824 – 3 June 1898) was a British politician and social reformer, now best remembered for having devised the Plimsoll line (a line on a ship's hull indicating the maximum safe draught, and therefore the minimum f ...

Standard State
In chemistry, the standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions. A superscript circle ° (degree symbol) or a Plimsoll (⦵) character is used to designate a thermodynamic quantity in the standard state, such as change in enthalpy (Δ''H''°), change in entropy (Δ''S''°), or change in Gibbs free energy (Δ''G''°). The degree symbol has become widespread, although the Plimsoll is recommended in standards, see discussion about typesetting below. In principle, the choice of standard state is arbitrary, although the International Union of Pure and Applied Chemistry (IUPAC) recommends a conventional set of standard states for general use. The standard state should not be confused with standard temperature and pressure (STP) for gases, nor with the standard solutions used in analytical chemistry. STP is commonly used for calculations involving gases that approximate an ideal ...

Plimsoll Line
The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line (positioned amidships), that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with a similar lessening effect upon buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. A waterline can also refer to ...

Plimsoll Shoe
A pump or plimsoll (British English; see other names below) is a type of athletic shoe with a canvas upper and rubber sole developed initially as beachwear. Pumps have solid rubber soles about 8 or 9 mm thick, to which the canvas is glued without coming up the sides (as on trainers). The effect when running is similar to running without shoes. The shoe originated in the United Kingdom, there called a "sand shoe". It acquired the nickname "plimsoll" in the 1870s. This name arose, according to Nicholette Jones's book ''The Plimsoll Sensation'', because the coloured horizontal band joining the upper to the sole resembled the Plimsoll line on a ship's hull, or because, just like the Plimsoll line on a ship, if water got above the line of the rubber sole, the wearer would get wet. In the UK plimsolls are commonly worn for schools' indoor physical education. Regional terms are common: around their area of origin (Liverpool, in northwest England) they are often referred to as "galos ...
