TABLE 145.— CUBICAL EXPANSION OF LIQUIDS 153 



If Vo is the volume at 0° then at t° the expansion formula is Vt = Vo (\ + at -\- 

 pt 2 ~\- yf). The table gives values of o, /3 and y and k, the true coefficient of cubical 

 expansion, at 20° for some liquids and solutions. At is the temperature range of the 

 observation.
