 CUBICAL EXPANSION OF SOLIDS. 



If V2 and v\ are the volumes at t<2, and ti respectively, then vz = vi (i + CAt), C being the 

 coefficient of cubical expansion and At the temperature interval. Where only a single temperature 

 is stated C represents the true coefficient of cubical expansion at that temperature.*
