Acryogenic vacuum pump works by condensing vapors onto some absorbent medium. this is an efficient and clean way to pump a system in a research environment. the term cryo means cold, which indicates that these types of vacuum pumps contain a refrigerant cycle to cool the internal parts. the temperature difference between the inside and outside of a typical cryogenic pump is δ=300 ∘c . derive an expression to convert this difference into fahrenheit and express the answer
