 CUBICAL EXPANSION OF SOLIDS. 



If Vi and V\ are the volumes at /2 and t\ respectively, then 7/2 = ^1 (' + CLt), C being the 

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

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