Calculate the RMS speed of helium atoms near the surface of the Sun at a temperature of about 5300 K.

RMS velocity,

Explanation:

We need to find the RMS speed of helium atoms near the surface of the Sun at a temperature of about 5300 K.

The formula for RMS speed of a gas is given by :

Where

R is ideal gas constant, R = 8.314 J /mol K

T = 5300 K

m is molar mass of Helium,

Substituting all the values in above formula :

So, the RMS speed Helium atoms 5748.75 m/s.
