What is more compressible? Nitrox or breathing gas?

Answer 1

There is no difference they both compress the same ,

Dalton's Law

John Dalton studied the effect of gases in a mixture. He observed that the Total Pressure of a gas mixture was the sum of the Partial Pressure of each gas.


P total = P1 + P2 + P3 + .......Pn
The Partial Pressure is defined as the pressure of a single gas in the mixture as if that gas alone occupied the container. In other words, Dalton maintained that since there was an enormous amount of space between the gas molecules within the mixture that the gas molecules did not have any influence on the motion of other gas molecules, therefore the pressure of a gas sample would be the same whether it was the only gas in the container or if it were among other gases.

This of course assumes that temp and all other variables are constants.
