Which characteristic of gas is used in supplying oxygen cylinders to hospitals?

Oxygen can be compressed so that a large amount occupies relatively small space.

Well...this question has two answers. The characteristic of gas that would be used in supplying oxygen cylinders to hospitals is compressibility. Oxygen cylinders are filled to, depending on the gas company you buy yours from, between 2000 and 2500 psi.

Normal atmospheric pressure is 15 psi. (I know I should give you these numbers in kPa, but my gauge is calibrated in PSI.) Compressing the oxygen allows you to fit over 150 times the uncompressed volume in a cylinder. However!

With the exception of very small rural hospitals, no hospital or city fire department wants to receive compressed oxygen. They use so much oxygen that the only efficient way to deal with it is to receive it in liquid form and regasify it as needed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
