Calculate the speed that a gas-phase oxygen molecule would have if it had the same energy as an infrared photon (A = 10nm), a visible photon (A = 500 nm), an ultraviolet photon (A = 100nm) and an X-ray photon (A = 0.1 nm). What temperature would the gas have if it had the same energy as each of these photons? Use the root mean square speed, Vms = | v2|12= V (3kT/m), for this calculation. %3!
