A cryogenic vacuum pump works by condensing vapors onto some absorbent medium. This is an efficient and clean way to pump a syst
em 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=303 ∘C . Derive an expression to convert this difference into Fahrenheit and express the answer.
