Video: The Sensory System: Definition, Parts & Functions. This lesson will examine how the sensory systems are integrated and how they function as a whole. Instead of telling you ears hear and eyes see, we will examine how these systems are actually very similar in terms of reception, signals, and translations.
Mercury is a silvery-white metal element that is liquid at ordinary room temperature; it has no taste or smell. It occurs as metallic mercury (Hg), as cinnabar (HgS) and in perhaps 25 other in organic mineral compounds. The elemental form (Hg) vaporizes at any temperature down to almost 40Â° below zero. The vapor also has no taste or smell. The specific gravity of mercury is 13.546; therefore, it is heavier than lead and, like lead and other heavy metals, it is a potent poison. Exposure to metallic mercury or mercury compounds, even in small quantities over a period of time, can cause severe poisoning.
Mercury is a metal that is liquid at room temperature. When combined with gold or silver, it becomes viscous, its consistency becoming similar to that of butter. Mercury gilding is the process in which mercury is mixed with gold to make an amalgam that is applied to the surface of an object.hen combined with gold or silver, it becomes viscous, its consistency becoming similar to that of butter.
