Exercise 48

A sample of oxygen (O 2 ) and another sample of nitrogen (N 2 ) are at the same temperature. (a) The rms speed of the nitrogen sample is (1) greater than, (2) the same as, or (3) less than the rms speed of the oxygen sample. Explain. (b) Calculate the ratio of the rnrs speed in the nitrogen sample to in the oxygen sample.
