It will be seen that a good straight line is obtained, the relation given being 
2573 A Xo = -fi + 142-25, 
which shows that E5- s = 142'25, and that the specific heat of the liquid solute may be 
taken as constant for all dilutions and has the value 
40

and also that the suggested relation holds, giving 
As m = 6\ v -s m = 2573 A Xo /H = 2573 A%, 
or 
A%/ A?% = 2573. 
W e are now able to interpret the experimental results accurately and quantitatively 
on the hypothesis that the specific heat of the solute remains constant for isothermal
