Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.

What is diffusion in liquid and in gas?
Gases the most, then liquids. Solids generally don't diffuse.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
What are three macromolecules that cannot diffuse across a cell membrane?
Any protein, any fat, and most polypeptides.
What characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
What can diffuse directly across the plasma membrane of a eukaryote cell?
Most small non polar molecules can diffuse across the membrane. Water is polar but diffuses across the cell through aquaporins. There are also proteins that actively transport substances across the cell membrane such as ions (ex.The Na/K pump). It can get a little confusing. I tried to be as simple as possible. I don't know if this is what you were looking for.
Gases diffuse most efficiently across a respiratory membrane if the membrane is?
Thick and moist
Can oxygen diffuse across a cell membrane?
Yes, how else would our cells obtain oxygen?

What gases diffuses most rapidly at stp?
diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond) and mass. So the lightest most un-reactive gases will diffuse the quickest. Helium would seem to be the best contender. diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond) and mass.

Why do gases duffuse quickly but most solids do not?
Its down to the molecules in the substance, in gases they are not that close to each other so they can move around quicker and faster so hence diffuse quicker in solids or most they are that tight they can not move are as easily.

When is a cell most likely to diffuse into a cell when?
I believe the answer is when it is uncharged.
What prevent a cell to become too large?
A cell is dependent on nutrients and other molecules diffusing into the cell. This process works most efficiently when the surface area to volume ratio is higher. If there were a cell the size of a person, the necessary nutrients would not diffuse fast enough for cell function.
What gases are most important to life?
what are that ten most improtana gases in life on earth
