Exercise:
Calculate the speed of helium isotopeHe atoms near the surface of the Sun at a temperature of about thO.

Solution:
The kinetic energy of at that temperature is E frac kT frac nck T E so the speed of these isotopeHatoms mass approximately u is v sqrtfracEm sqrtfrac frac kTm sqrtfrackTm sqrtfrac Em v approx vS vP v sqrtfrackTm v approx vS vP
