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

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
