So, for example, at standard pressure and 20 Kelvins deuterium is a liquid and has a density of 165.6 g/L. At higher pressures and lower temperatures, its density is more. (Though solid deuterium is less dense than liquid deuterium.) So though the deuterium slush in the engineering hulls' storage tank is likely to be around 165.6 g/L, the antideuterium may be held at a higher pressure and have a h
