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.
Best Answer: Mercury is a liquid metal at room temp, never a solid or powder. However, it can be combined with other things to form an alloy, such as with silver, or a chemical like the disinfectant Mercurochrome, which are solids and can be made into powders.m guessing it is mercury (metal which is liquid at room temp) which has been cooled below its freezing point and then crushed to make powder Ps.
