14. DIFFUSION COEFFICIENTS: GASES IN WATER AT VARIOUS TEMPERATURES 

 Methods: U = unspecified; A = measurement of the volume of gas diffusing per unit time into a gel of 1-2% agar in 

 water, in temperature range 0-30°C; B = measurement of the volume of gas diffusing from a gas bubble into the 

 surrounding water in the temperature range 21-37°C (the relative values of the coefficients for various gases 

 obtained by this method were converted to absolute values by means of Dh^ as measured directly [l] ); C = colori- 

 metric measurement of the diffusion velocity of O^ by addition of 0.03-1% hemaglobin as indicator; D = measurement 

 of the volume of gas diffusing per unit time into a tube filled with gas-free water; P = polarographic measurement 

 with the dropping- mercury electrode; T = measurement of the velocity of diffusion within a tube of 1 cm diameter 

 filled with water or a 2% solution of agar in water.
