Cryogenic 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 t = 300 ∘ c . derive an expression to convert this difference into fahrenheit and express the answer.

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
