Table 176. 



VOLUME OF PERFECT GASES. 



Values of 1 + .00367 ^ 



The quantity- i + .00367^ gives for a perfect gas the volume at P when the pressure 

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

 of the volume or the pressure at 0°. 



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

 and 10^ C. by tenths of a degree. 



(b) This part gives the values of i +.00367 ^ for values of / between — 90° and + 1990° 



C. by lo"^ 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 (i) 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 (h) the number .... 3.49560 



And for 2.2 in table (,ii) the decimal .00807 



Hence the number for 682.2 is 3-50367 



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



+ 399° C. by degrees, 

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

 C. by 10° steps.
