The coefficient of a gas depends on
Solubility , molecular weight
Solubility , diffusion distance
Partial pressure of the gas , diffusion distance
Surface area of gas exchange ,molecular weight
Molecular weight is directly proportional to the gas diffusion
True
False
Surface area is directly proportional to the gas diffusion
O2 ha lower solubility than CO2
O2 is more diffusionable than CO2
