Table 112. 

 VOLUME OF CASES. 



Values ol 1 + .00367 t. 



The quantity i -f- .00367 i gives for a gas the volume at t° when the pressure is kept 

 constant, or the pressure at t° when the volume is kept Lonstant, in terms of the 

 volume or the pressure at 0°. 



(a) This part of the table gives the values of 1 + .00367 / for values of / between 0° 

 and 10^ C. by tenths of a degree. 



(b) This part gives the values of i +.00367/ for values of t between — 90° and + 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 (b) table and the actual temperature. For example, let the 

 temperature be 682°.2 : 



We have for 680 in table (l>) the number .... 3.49560 



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



Hence the number for 682.2 is . ..... 3.50367 



(C) This part gives the logarithms of i + .00367 ^ for values of i between — 49° and 



-|- 399° C. by degrees, 

 (d) This part gives the logarithms of i + .00367 1 for values of t between 400° and 1990° 

 C. by io° steps.
