1. A) Calculate thespeed that a gas phase oxygen molecule would have if it had thesame energy of an infrared photon (λ = 5000 nm), avisible photon (λ = 500nm), an ultraviolet photon(λ = 100 nm), an X---ray photon (λ = 0.1 nm). Use theRMS speed for a molecule: √(3kT/M).
B) What temperaturewould the oxygen molecule have to be if it had the same energy forthe above photons?
