Flask is a British unit of mass or weight in the avoirdupois system, used to measure mercury. [1] [2] [3] ... 1 flask (mercury) ≡ 34.47302012 kg References
Mercury was a propellant for early ion engines in electric space propulsion systems. Advantages were mercury's high molecular weight, low ionization energy, low dual-ionization energy, high liquid density and liquid storability at room temperature. Disadvantages were concerns regarding environmental impact associated with ground testing and ...
Mercury is one of four terrestrial planets in the Solar System, which means it is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). [4] Mercury is also smaller—albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan.
The choice of solar mass, M ☉, as the basic unit for planetary mass comes directly from the calculations used to determine planetary mass.In the most precise case, that of the Earth itself, the mass is known in terms of solar masses to twelve significant figures: the same mass, in terms of kilograms or other Earth-based units, is only known to five significant figures, which is less than a ...
As for how much mercury is dangerous, the exact number is up for debate. Per Ciarametaro, tissue concentration of 100 ng/mL of methylmercury or greater is commonly considered 'high'.
The temperature of Mercury's exosphere depends on species as well as geographical location. For exospheric atomic hydrogen, the temperature appears to be about 420 K, a value obtained by both Mariner 10 and MESSENGER. [4] The temperature for sodium is much higher, reaching 750–1,500 K on the equator and 1,500–3,500 K at the poles. [15]
