When gases are diffusing through liquids, for example across the alveolar membrane and into capillary blood, the solubility of the gases is important. The more soluble a gas is, the faster it will diffuse. Carbon dioxide is inherently more soluble than oxygen, and thus diffuses much faster than oxygen into liquid.

The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. The oxygen and nitrogen molecules in air at normal room temperature are moving rapidly at between 300 to 400 metres per second.

As we can see that nitrogen gas will diffuse faster than oxygen due to its lower molecular weight, we can now conclude that the above statement is true. Additional Information: As we all know that diffusion is the process by which particles of matter flow from a higher concentration to a lower concentration.

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.

An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure.

If you compress your gas enough (and lower the temperature), eventually the particles will come close enough that they start to attract each other, and then your gas turns into a liquid. You can’t compress a liquid as much simply because there isn’t as much space between particles. Highly active question.

When they compressed ice at low temperatures, instead of transforming into a high-pressure crystalline form where the atoms are organized into a lattice pattern, the ice converted to an amorphous solid and the atoms were disorganized. They hypothesized that this was due to “melting” of ice at high pressure.
