 Data and Results of Determination of Specific Heats. 



Let us consider first the effect of diluting the hydrochloric acid. 

 The solution HCl . 100 H2O weighs per gram molecule of hydrochloric 

 acid 36.46 + 1801 .5 grams. With a specific heat 0.9634 this gives 

 a molecular heat 1770.6. When 100 gram molecules of water have 

 been added to this solution, it then has a total molecular weight 

 3639.5 and a molecular heat capacity of 3571.8 calculated from its 

 specific heat 0.9814. The difference between the total molecular 

 heat capacities of these two solutions is 1801 .2 or almost the same as
