The lower the temperature, the greater the brine concentration. A January 2014 along the coast of the White Sea recorded that at an air temperature of −1 °C the brine salinity was between 30 and 35 psu while the salinity at sea was 28 psu. When the temperature was −12 °C the salinity of the brine increased to between 120 and 156 psu. [5]
As sea ice freezes, it rejects increasingly salty water, which drains through narrow brine channels that thread through the ice. The brine flowing through the brine channels and out of the bottom of the ice is very cold and salty, so it sinks in the warmer, fresher seawater under the ice, forming a plume.
The toy sinks when placed into water, but after a few seconds, enough water leaks in to react with the baking powder and produce carbon dioxide bubbles. The resulting foam creates just enough buoyancy in the toy for it to rise towards the surface of the water. When the toy surfaces, it capsizes, releasing the gas into the air. The toy sinks ...
The remains of the partial veil are seen as a skirtlike, floppy annulus usually about 1 to 1.5 cm (3 ⁄ 8 to 5 ⁄ 8 in) below the cap. The crowded white lamellae (gills) are free. The stipe is white with a scattering of grayish-olive scales and is 8 to 15 cm ( 3 + 1 ⁄ 8 to 5 + 7 ⁄ 8 in) long and 1 to 2 cm ( 3 ⁄ 8 to 3 ⁄ 4 in) thick ...
Peter Sinks is a natural sinkhole in northern Utah that is one of the coldest places in the contiguous United States.. Peter Sinks is located 8,100 feet (2,500 m) above sea level, in the Bear River Mountains about 20 mi (32 km) east of Logan, within the Wasatch-Cache National Forest.
A group of hikers encountering quicksand on the banks of the Paria River, Utah Quicksand warning sign near Lower King Bridge, Western Australia. Quicksand is a shear thinning non-Newtonian fluid: when undisturbed, it often appears to be solid ("gel" form), but a less than 1% change in the stress on the quicksand will cause a sudden decrease in its viscosity ("sol" form).
A heat sink (also commonly spelled heatsink, [1]) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature.
A butler's sink is a rectangular ceramic sink with a rounded rim which is set into a work surface. [5] There are generally two kinds of butler's sinks: the London sink and the Belfast sink. [ 5 ] In 2006, both types of sinks usually were 61 centimetres (24 in) across and 46 centimetres (18 in) front-to-back, with a depth of 22.5 centimetres (8. ...
