TCB Featured Article
Main article: Absolute zero
Absolute zero is the zero point temperature in Kelvin and Rankine temperature scales in which there is no motion. As heat is added to the system then motion increases, and may be measured by a thermometer. |

TCB Featured Element
Main article: Chromium
Chromium was discovered by Louis-Nicholas Vauquelin. It is a steely-gray, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. The elements name originates from the Greek word, chrōma, meaning colour, because many of its compounds are intensely coloured. Chromium metal is of a high value due to its high corrosion resistance and hardness. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration when adding metallic chromium to form stainless steel. This application, along with chrome plating currently comprises 85% of the commercial use for the element, with the application for chromium compounds in the remaining 15%. |
