TABLE 112. 

 VOLUME OF CASES, 



Values ol 1 + .00367 *. 



The quantity i + .00367 t gives for a gas the volume at < when the pressure is kept 

 constant, or the pressure at ( when the volume is kept constant, in terms of the 

 volume or the pressure at o. 



(t) This part of the table gives the values of i -f .00367 1 for values of t between o 

 and 10 C. by tenths of a degree. 



(1) This part gives the values of i + .00367 / for values of / between 90 and 4- 1990 

 C. by 10 steps. 



These two parts serve to give any intermediate value to one tenth of a degree by a sim- 

 ple computation as follows : In the () table find the number corresponding to 

 the nearest lower temperature, and to, this number add the decimal part of the 

 number in the (a) table which corresponds to the difference between the nearest 

 temperature in the (*) table and the actual temperature. For example, let the 

 temperature be 682. 2 : 



We have for 680 in table (6) the number .... 3-495 60 



And for 2.2 in table (a) the decimal .00807 



Hence the number for 682.2 is 3-53 6 7 



(0) This part gives the logarithms of i + .00367 1 for values of t between 49 and 

 + 399 C. by degrees. 



(d) This part gives the logarithms of i -+-.00367 / for values of t between 400 and 1990 

 C. by 10 steps. 



(a) Values of 1 + .00367 / for Values of / between and 10 G. by Tenths 

 of a Degree.
