Estimate the average thermal energy of a helium atom at the temperature of 10 million kelvin (the typical core temperature in the case of a star).

At temperature, \mathrm{T}=10^{7} \mathrm{~K}, we have

Average thermal energy will be =(3 / 2) \mathrm{kT}

=(3 / 2) \times 1.38 \times 10^{-23} \times 10^{7}

We get,

=2.07 \times 10^{-16} \mathrm{~J}

As a result, the average thermal energy of a helium atom at the core of a star is 2.07 \times 10^{-16} \mathrm{~J}
