Table 222. 

 COEFFICIENTS OF THERMAL EXPANSION. 



22$ 



Coetflclents ol Cnlilcal Expansion ol Llaolds. 



This table contains the coefficients of expansion of some liquids and solutions of salts. When not otherwise stated 

 atmospheric pressure is to be understood. T gives the temperature range, C the mean coefficient of expansion 

 for range T in degrees C, and A-i the authority for C. a, p, and y are the coefficients in the volume equation 

 v, =: z/fl (i + a^ + /8/= + yfi), and m the mean coefficient for range o"-ioo° C, and Wj is the authority for these.
