At what temperature does the rms speed of hydrogen molecules exceed their most probable speed by 200 m/s (kelvin, nearest integer)? $m = 2 \times 1.66 \times 1 0^{- 27}$ kg.

Answer:

95.00

Solution:

$v_{r m s} - v_{p} = \frac{k T}{m} (3 - 2) = 200$ . So $T = (\frac{200}{( 3 - 2 ) \frac{k}{m}})^{2} = 95$ K.
