 | | It may he noted that if comparison be made with water at 4, the relative density is the same as the absolute density, since the unit of mass in the C.G.S. system is the weight of a cubic centimetre of water at this temperature. |
 | | Similarly in the case of the weighing in water, account must be taken of the buoyancy of the weights, and also, if absolute densities be required, of the density of water at the temperature of the experiment. |
 | | pressure, Wi the weight in water, atmospheric conditions remaining very nearly the same; p is the density of the water in which the body is weighed, a is (I +at) in which a is the coefficient of cubical expansion of the body, and I is the density of the air at 10, p mm. |
