Abstract
Some time ago a new flow method for comparing the specific heats of gases was described by P. M. S. Blackett, E. K. Rideal, and the author.* It is the purpose of this paper to give an account of further developments of the method, and of the results which have been obtained by it from room temperature up to 370° C. for air, oxygen, nitrogen. The chief improvements in the apparatus over that described previously have been a different construction of the calorimeter, ensuring more uniform temperature surroundings for the tube ; potentiometric measurement of the temperature differences ; double glands to the pump, eliminating leakage or contamination of the gas ; and automatic control of the pumping speed and heating current.This publication has 0 references indexed in Scilit:
