a- For H2 gas at 25 °C, calculate the ratio of the fraction of molecules that have a speed 2u to the fraction that have the average speed ū. How does this ratio depend on the mass of the molecules and the temperature? b- Calculate the ratio of the fraction of the molecules that have the average speed ū100ºC at 100 °C to the fraction that have the average speed ū25ºC at 25 °C. How does this ratio depend on the mass?
