The escape velocity from the moon is much smaller than that from the earth, only 2.38 km/s. at what temperature would hydrogen molecules (molar mass is equal to 2.016 g/mol) have a root-mean-square velocity vrms equal to the moon’s escape velocity?

457.8394 K

Explanation:

= Escape velocity = 2.38 km/s

T = Temperature

R = Gas constant = 8.314 J/mol K

M = Molar mass = 2.016 g/mol

The rms velocity of a molecule is given by

Here,

The temperature of the hydrogen molecule would be 457.8394 K

i think the answer is a and b

i wish you luck
