👉 Rarefiable is a term used in the field of chemistry and physics that refers to a substance that has an extremely low density, which makes it difficult for particles of other substances to pass through it. This property allows rarefied gases to be used in applications where high pressure or temperature are required, such as in refrigeration systems or in rocket engines. Rarefication is the process by which a gas is reduced in volume to a state where its density is below that of air. Raref
