The higher the dewpoint is, the more moisture that is in the air. The higher the dewpoint is above 65 F, the stickier it will feel outside (feels like you have to breathe in a bunch of moisture with each breath). 75 F or above dewpoint, the air really feels sticky and humid. RH can be more difficult to explain.
Unlike all of the other planets in the Solar System, Mercury is just bare rock. It does have a tenuous atmosphere, but ground and space-based observations see just the gray rocky color of Mercury. This gray color comes from Mercuryâs molten surface that cooled and hardened billions of years ago after the formation of the [â¦]
A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.Contents. On the periodic table of elements, the chemical symbol for mercury is Hg, from the Latin word-Hydrargyrum-meaning liquid silver. 2  For quite some time, we have known that high concentrations of mercury can be toxic to humans; the first account of mercury poisoning was recorded as early as 50 B.C.
