Abstract
In a method for measuring density and related properties by weighing a solid body while it is suspended in a fluid, there are significant advantages if the fluid hasa) a density that is smaller than the density of water;b) a surface tension that is significantly smaller than the surface tension of water;c) a rate of evaporation that is slower than the evaporation rate of water, due to a vapor pressure that is smaller than the vapor pressure of water-by at least a factor of 2; andd) a water absorption of less than 1%. Preferably, the fluid contains at least one cyclosilane.
