Oxygen gas, O2, is a molecule that is necessary for living things to survive. We breathe in oxygen from the atmosphere around us, and it travels through our body and ends up in our cells. Oxygen is necessary for powering the process of cellular respiration....
aThe speed of diffusion of two kinds of gas molecules of oxygen and nitrogen on the surface of molecule sieve is different, the gas molecule(O2) smaller in diameter spreads faster, more entry into millipore of carbon molecules sieve, the relatively slower gas molecule (N2)bigger in diameter sp...
