PETTERSSON, ON WATER AND ICE. 



Table V. Ice frorr 



Specific gravity (ice-water) at q^^ = 1.0053. 

 A. Ice. 

 L — 49. 1 840 cc at o' C 

 Q = 11.5978 » » — 2\2 C 

 Wi = 34.9040 » » o' C (vvater) 

 q = 0.00017905 [Regn.] 

 g = 0.00002753 



The change in the volume by the liquefaction of the ice was determined bet\\-ee 

 2°. 20 C and — 0^.39 C 



Total change of volume between — 2°. 2 C & — 0^.39 C = 2.67985 cc. 

 Calculated for i cc. of the water = 0.076772 cc. 



Volume of i cc. of water at 0° as ice at — 2°. 2 C = 1.076784 cc. 



Increase of volume of the water, if solidif at — 2^.2 C = 0.076650 cc.
