Question

If the rms speed of methane gas in the Jupiter’s atmosphere is 471.8 m s^-1 , show that the surface temperature of Jupiter is sub-zero.

Answer 1

RMS speed of methane gas (v_rms) = 471.8 ms^-1 

Molar mass of methane gas (M) = 16.04 g per mol

M = 16.04 x 10^-3 kg/mol

Gas constant R = 8.31 mol^-1 k^-1
