Answer to: The mass of a Helium-4 nucleus is 6.7x10^-27 kg and the radius is 1.9 fm (femtometres). True volume is usually measured with a gas stereopycnometer (helium or nitrogen), excluding interparticular volume (Mohsenin 1980; Zogzas and others 1994). 2. This air pressure, density, and temperature vs. altitude calculator determines the atmospheric pressure, air density, temperature and the speed of sound for a given altitude and a temperature offset using the International Standard Atmosphere (ISA) and the US Standard Atmosphere 1976 (USSA) models, which are essentially the same in the interval of 0-86 km. It is preferable to use helium, as its small molecular diameter makes it possible to access pores of up to 3.5 Å (Karathanos and Saravacos 1993). Density of crude oil, Density of fuel oils, Density of lubricating oil and Density of jet fuel as function of temperature. Therefore, helium filled balloons will rise at ground level.
