It spreads evenly throughout its containers/surroundings.
When a gas diffuses, it merely spreads out through the volume available to it. It will accordingly become less intense.
It diffuses equally throughout the container so that the concentration of that gas is equal throughout it as long as the lid is on.
Gas diffuses in space.
carbon
Oxygen diffuses into cells. Carbon dioxide diffuses out.
Co2
The rate of diffusion of a gas is inversely related to the molecular weight of that gas. The lighter the gas, the faster it diffuses. Hydrogen is the lightest of all gases having a molecular weight of only 2. Thus it diffuses faster than all others.
Oxygen
Nitrogen
CO diffuses faster than CO2 because it is a smaller molecule
o2 diffuses into blood from alveoli of lungs through the respiratory membran.
