The rate of diffusion change would increase if the PO₂ in the capillaries was 40 mmHg and the PO₂ in the muscle cell changed from 40 to 20 mmHg.

Simple diffusion is the movement of molecular substances from a region of higher concentration to lower concentration. The mechanism with which the movement of O₂ travels from the blood to the body tissues takes place with the use of simple diffusion.

Now, if PO₂ changes from 40 → 20 mmHg in the muscle cells, and the PO₂ in the blood = 40mmHg. It implies that the pressure gradient(P) has increased. As such, there is an increase in the rate of diffusion of oxygen from the blood to muscle cells.

The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.

The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.

So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.

Answer:

I believe the answer is compressed

Explanation:

The answer may be a slightly different word, but if it's looked at by a human and not a robot compressed should work too

Gases can be compressed by applying high pressure. Thus large volume of oxygen can be contained in a tank by compressing the gas with high pressure.

Gases are substances in state where its molecules are located far apart and are able to spread in the surroundings. This property of spreading based on the concentration difference is called diffusion.

Thus, gases diffuse from high concentrated area to lower concentration region. Gaseous substances does not have a certain volume, mass or shape. But when they are collected into a container then the volume will be that of the container.

in liquid state, molecules are some more closer in comparison to gases and an intermolecular attraction of force bind these molecules together to have a certain volume and mass. Whereas in solids, all the molecules are tightly packed.

Gases can be liquified by applying high pressure at low temperature so that the distance between molecules can be decreased and an intermolecular force of attraction occurs there.

So that large volume of gases can be collected  to a tank by compression using high pressure.
